Part IThe Story
Three Minutes Before Ten
At 9:57 on the morning of May 20, 2025, the trading floor of the Hong Kong Stock Exchange held one of the few crowds left in finance that still wears a suit and tie. Andy Mok, a Wharton graduate who had come to watch, stood beside a partner from Linklaters. The lawyer leaned over and whispered that he hadn't felt this kind of buzz since Alibaba. Three minutes later, the chairman of a battery company from a provincial city in northeastern Fujian struck a bronze gong, and $4.6 billion moved from the world's institutional investors into Contemporary Amperex Technology Co., Limited. It was the largest initial public offering anywhere on Earth that year.
The chairman was fifty-seven. His name, depending on who is saying it and to whom, is either Robin Zeng or Zeng Yuqun. He holds a doctorate in physics and, by then, Hong Kong citizenship. The night before the float he had said something unusual for a man about to become richer: "I don't want to be the rich guy. I want to share these riches to create a good society." It is possible to read that line as sincere. It is also possible to read it as the kind of sentence a Chinese billionaire in the Xi Jinping era learns to say before anyone asks. Both readings can be true at once.
Several people were notably absent from the celebration, and their absence was part of the event. Four months earlier, on January 7, the United States Department of Defense had added CATL to its list of "Chinese military companies." In April, the House Select Committee on the Chinese Communist Party had written to JPMorgan Chase and Bank of America asking them to withdraw from the deal. By July the committee would subpoena the banks. The money came anyway, and it came from a revealing roster: Sinopec, the Kuwait Investment Authority, Hillhouse, Oaktree Capital Management, and a fund belonging to the Agnelli family, the Turin dynasty whose fortune was built on Fiat and the internal combustion engine. The family that helped teach Europe to drive was now buying a stake in what would replace the engine.
The shares surged. The company's market value rose to roughly $166 billion. By late summer the Hang Seng was up 30 percent for the year, and analysts were crediting the CATL float with pulling the Hong Kong market out of its post-"Liberation Day" slump. Mok later noted that the H-shares had traded 10 to 15 percent above the company's Shenzhen A-shares, a rare reversal. Foreign capital was paying a premium for the privilege of owning a company Washington had formally designated a threat.
None of this explains why the company's Chinese name means what it means.
In English it is Contemporary Amperex Technology, a name built to disappear, the corporate equivalent of a gray suit. In Chinese it is 宁德时代, Ningde shidai: "the Ningde Era." Ningde is the city where Zeng was born in March 1968, in poverty, near a mountain village whose farmers in the 1960s looked like stock footage of the Chinese countryside. It is the city where Xi Jinping served as local Communist Party chief from 1988 to 1990. It is the city, still, that recruiters in Shenzhen and Shanghai regard as a backwater. One name was made to face the world. The other faces home. Nearly everything about Robin Zeng comes in such pairs, and the interesting question is never which one is real.

The Man Who Said It Couldn't Be Done
The founding myth of CATL begins with a refusal.
In 2010, Herbert Diess was running purchasing for BMW. He would later become chief executive of Volkswagen, but at that moment he was a man with an odd errand. He was traveling the world trying to persuade companies that made batteries for mobile phones to start making batteries for cars. He tried Europe first, including Bosch. Nobody bit. So he went to see a Chinese engineer running a lithium battery subsidiary of the Japanese electronics conglomerate TDK.
Diess told the story himself, in an internal Volkswagen meeting in May 2022. He described Zeng's reaction as dismissive. It was, Zeng told him, impossible for him to build batteries that big.
What happened next is the hinge. Within about a year, Zeng had led a group of Chinese investors to buy 85 percent of TDK's nascent electric-vehicle battery business. BMW became its first major customer, moving its business away from A123, the American battery supplier with factories in Massachusetts and Michigan. A decade later, Zeng was characteristically flat about the debt.
— Robin Zeng, to Handelsblatt, 2020Diess brought our company into the car battery business. I am grateful to him for that.
There is a detail from the BMW courtship that belongs in the permanent record of how industrial empires actually get built. The German automaker sent over its requirements. They ran to about 800 pages. According to Yunfei Feng, a research associate at IMD Business School, it was Zeng himself who read them line by line. He did not hand them to an applications engineer or a compliance team. The chairman read every page.
One way to understand Zeng is as a man who says no to the large thing and then reads all 800 pages of it. The refusal and the reading are not opposites. They come from the same temperament: an engineer's suspicion of anything that has not yet been specified down to the line item. "Impossible" in that first meeting was probably not a judgment about the future. It was a statement about the present, about what could be built with the tools then on the table. When the tools changed, so did the answer.
The car Zeng's first BMW batteries went into was the Zinoro 1E, sold under BMW Brilliance, the Chinese joint venture. It sold modestly, which is the polite word. It did not matter. The value of the contract was not the volume. It was the education: research, design, testing, and the brutal discipline of German automotive qualification, absorbed by a company that did not yet have a name anyone outside Fujian would recognize. Later, Zeng and his executives would say that the company applied the management styles of TDK and Huawei. The Japanese taught process. Huawei taught ferocity. BMW taught what a car company would actually demand. Zeng seems to have taken notes on all three.
Three Months at the State Firm
China in 1989 did not ask its university graduates where they wanted to work. The state assigned them. Zeng had come out of the village, out of what one chronicler calls a large peasant family with at least two brothers, through the best local high school, and into Shanghai Jiao Tong University, one of the most selective engineering institutions in the country. He studied in the School of Naval Architecture, Ocean and Civil Engineering. He learned to design ships.
After graduation he was assigned home, to a state-owned enterprise in Fujian, which by most accounts was a shipbuilding concern. By the standards of the village, this was already the end of a success story. A peasant's son had gone to Shanghai and come back with an iron rice bowl: guaranteed employment, modest prestige, a pension at the end.
He quit after three months.
He went south, to Dongguan in Guangdong, which at the end of the 1980s was becoming the workshop of the world. He took a job as an engineer at SAE Magnetics, a Hong Kong–registered component maker in the orbit of TDK, and stayed about a decade, rising to research and development technical director. The ship designer became a man who understood factories: yields, tolerances, the patient tyranny of process control.
The Dongguan years are the least documented and probably the most important. What Zeng learned there was not a chemistry. It was a sensibility: that in physical manufacturing, the difference between a brilliant prototype and a business is almost always a thousand boring decisions about equipment and materials and consistency. Decades later, asked by Nicolai Tangen of Norway's sovereign wealth fund why European battery makers kept failing to scale, he answered with the clipped diagnosis of a man who had watched it happen from the inside. They had the wrong design, the wrong process, and the wrong equipment. With all three mistakes together, he said, there was no way to succeed.
In 1999, he and two colleagues, Liang Shaokang and Chen Tanghua, founded Amperex Technology Limited (ATL) in Hong Kong, with its first factory in Dongguan. The company spent $7 million, a fortune for three engineers, to license lithium polymer battery patents from Bell Labs. The licensed technology did not work well at first. Lei Xing, formerly of China Auto Review, recalled that when the company bought that American patent, Zeng worked on improving the battery design himself. By 2001, ATL had shipped a million units. In 2003 it entered Apple's supply chain. By 2012, ATL held close to half of the global market for polymer lithium-ion batteries, the soft, flat cells inside phones and laptops.
He was also, somehow, still in school. He finished a master's in electronics and information engineering at South China University of Technology in 2001, then a doctorate in physics at the Institute of Physics of the Chinese Academy of Sciences in 2006. That was the year after he had already made his first fortune. Most founders collect degrees before they start companies. Zeng collected them during and after, the way some men collect patents: as proof of work.
Growth had a cost. ATL's expansion diluted the founders' equity heavily, and in June 2005 TDK bought 100 percent of the company for $100 million. Zeng stayed on to run it. On paper, he had cashed out. In practice, he had become a manager of a Japanese subsidiary, and he was about to discover what that meant inside China.
Eighty-Five Percent
The Chinese government began subsidizing electric vehicles in 2009. ATL, now Japanese-owned, had already started an R&D division for car batteries. In 2008, Zeng had set up Ningde Amperex Technology, planting the first piece of the operation in his hometown. In 2010, Fujian province named him to its "Hundred Talents Program." The direction was clear. The ownership was a problem.
Beijing had decided that batteries were strategic, and in 2011 it made that decision concrete. Foreign automakers that wanted to sell electric cars in China and collect subsidies of up to $19,300 per car for their buyers would have to transfer crucial technology to a domestic company. A battery business owned by a Japanese parent was not going to be the national champion of a Chinese strategic industry. Whatever ATL could become in cars, it could not become it as a TDK subsidiary.
So at the end of 2011, a group of Chinese investors led by Zeng and Huang Shilin, who would become his long-serving vice chairman, acquired 85 percent of TDK's electric-vehicle battery business. TDK kept 15 percent. In 2015, a different group of Chinese investors bought that last slice. In 2017, Zeng fully exited ATL. The two companies, born of the same lab and the same founders, were now strangers.
The financial terms of the 2011 transaction have never been disclosed. When The New York Times asked in 2021, TDK referred questions to CATL, and CATL said only TDK could discuss what had been paid. What is known is the outcome. By the end of that year, TDK's market capitalization was about $16 billion. CATL's was almost $240 billion.
It is tempting to read the episode as a heist, and some have. It is more accurate to read it as a lesson Zeng learned once and never forgot. Ownership is not a financial fact in China. It is a political one. ATL's sale to TDK had been the correct decision for three founders who needed capital in 2005. By 2011 it had become a cage. Pandaily, summarizing his public statements, notes that Zeng made sure CATL remained entirely Chinese-owned and emphasized that point publicly. The man had paid tuition on the subject, and the tuition was a company he had built and could no longer fully use.
There is an irony here that no one involved seems inclined to discuss. CATL was midwifed by a German purchasing manager's persistence, a Japanese parent's sale, and a Chinese regulation designed to pry technology away from foreigners. Its first customer was Bavarian. Its legal name was built for international buyers. Its founding act of national self-assertion was, in practical terms, a negotiated transaction with Tokyo.
The Nail
In 2020, as the pandemic arrived, CATL faced a crisis that came not from abroad but from Shenzhen.
BYD, the automaker and battery maker backed by Warren Buffett, released a video. It imitated a Chinese government safety test in which a nail is driven through a single battery cell. In BYD's video, the cell exploded in a fireball. BYD did not name the manufacturer, but the cell's lithium-cobalt chemistry resembled what CATL and the South Korean producers used. BYD's own bet was a different chemistry. The video was, in effect, an advertisement written in fire.
Chinese officials responded quickly. They dropped the nail test.
According to documents reviewed by The New York Times, a new regulation appeared two months later. It replaced the single-cell test with a requirement that an entire battery pack contain a fire for five minutes, closer to what other countries required. The regulation listed who had drafted it. First on the list, ahead of the government's own vehicle testing agency, was CATL.
The episode did not expose anyone to unsafe batteries. Other countries had never required a nail test. But the order of names on that document is about as precise an X-ray of the relationship between Zeng's company and the Chinese state as anyone outside Beijing is likely to get. The regulated company held the pen.
— Michael Dunne, former GM executive in Asia, to The New York Times, 2021CATL definitely seems like it's the concept and creation of a master plan.
The plan, if that is the word, has a paper trail. Within a year of founding CATL, Zeng set up a subsidiary in Qinghai province, in China's far west, where dried-out salt lake beds sit over thick brine rich in lithium. Beijing wanted development in its poorer western regions. CATL wanted the lithium. People familiar with the company told The Times that CATL locked in contracts for the richest deposits. Chinese policy banks, the state lenders that finance projects too risky for commercial banks, provided more than $100 million to CATL projects in Qinghai. The provincial government added about $33 million between 2015 and 2017. In 2015, Beijing published Made in China 2025, which named electric vehicles among the industries the country meant to dominate within a decade.
Then came the rule that turned a strong position into a captive market. Subsidies would go only to electric cars whose batteries were made by Chinese companies. General Motors had not been told. In 2016 it began shipping Buick Velite electric cars in China with batteries made by the South Korean firm LG. Buyers and dealers found local officials denying them subsidies. GM switched heavily to CATL.
The results show up in the numbers. In 2016, CATL was the world's third-largest supplier of batteries for electric and hybrid vehicles, behind Panasonic and BYD. In 2017 it sold 11.84 gigawatt-hours of power battery systems and took first place globally for the first time. It never gave the position back. By 2020 its profit margin was 11.1 percent, in an industry where 5 percent counts as success. It still collected government subsidies that year equal to a fifth of its net income. In 2023 the subsidies came to the equivalent of $790 million, and by September 2024 Nikkei identified CATL as China's single largest corporate subsidy recipient, a position it had held since 2023.
The capitalization table tells a quieter version of the same story. Before CATL's Shenzhen IPO in June 2018, the company let a few outsiders in. Pei Zhenhua, who had set up a lithium processing venture with CATL, took a stake. So did Yu Yong, the largest individual shareholder in China Molybdenum, CATL's partner in the Congo, whose holding company came to control 1.69 percent. A fund called Guokai Boyu invested more than $100 million for 1.2 percent. Guokai Boyu was controlled by a private equity firm co-founded by Alvin Jiang, grandson of the former Party chief Jiang Zemin. One of the fund's partners was an affiliate of National Trust, a firm that had in the past teamed up with the family of former premier Wen Jiabao. In 2016, BHR, a Chinese private equity firm on whose board Hunter Biden sat, paid about $15 million for 0.4 percent. By 2019 the stake was worth about $76 million. Asked about all of this, CATL pointed to its prospectus. All investors, it said, "acquired their shares based on common rules for private equity fund-raising activities."
The IPO made Zeng and his two vice chairmen, who together owned 40 percent of the company, enormously rich. In March 2020, with markets in Covid freefall, Zeng's fortune was about $9.7 billion. In May 2021, at $34.5 billion, he passed Li Ka-shing, the eighty-something patriarch of Hong Kong capitalism, to become the city's richest man. Li's fortune that day was $34.2 billion. It was a $300 million margin, with one man's lifetime of ports and property on one side and a battery maker's two years of stock gains on the other.
None of this subtracts from the engineering. It is the condition the engineering grew in. Industrial policy can create a protected market. It cannot make a lithium cell last 840,000 kilometers. The state built the greenhouse. Zeng still had to grow something in it that would survive outside.
You Can't Be Bigger Than Beijing
For most of CATL's rise, the most powerful man in electric vehicles who was not Elon Musk was, by design, almost invisible.
By 2022, Wired reported, Zeng ranked twenty-ninth on Forbes's list of the world's richest people. Bloomberg's 2021 ranking of green billionaires put him second, behind only Musk. Musk tweeted, sued, promised, and joked. Zeng rarely gave interviews. Pandaily called him the "Invisible King." Insiders described him to Wired as savvy, direct, even abrasive, which is worth noting because nothing about his public persona is abrasive at all.
Bill Russo, the former head of Chrysler's northeast Asia business, who now runs the Shanghai advisory firm Automobility, explained the silence in a single paragraph that functions as a field guide to Chinese capitalism after 2020.
— Bill Russo, founder of Automobility, to Wired, 2022In the West, the personality-cult style of leadership is something that's valued, encouraged, and celebrated. In China, it's dangerous. You can't be bigger than Beijing.
Zeng came up during a turbulent period for Chinese tech executives, when founders who had grown too loud found their companies, and sometimes their persons, abruptly managed by the state. He has, as MoneyWeek put it, learned the lessons. He is a member of both the 13th and 14th National Committees of the Chinese People's Political Consultative Conference and a vice chairman of the All-China Federation of Industry and Commerce. He speaks of Confucius and "lifelong learning and continuous moral improvement." He has distilled his own management philosophy into a Confucian triad: refine yourself, enable others, strive to innovate. In 2013 the state gave him the National May 1 Labor Medal, an honor whose name sounds made for a steelworker. In 2020 his hometown honored him as an outstanding contributor under the banner "Weak Bird First Flies, Dripping Water Wears Through Stone," a phrase from Ningde's own anti-poverty lexicon.
His silence is not empty, though. It is selective. When it serves CATL, the invisible king speaks plainly enough.
In 2023, when Musk returned to Beijing, his first meeting was not with a minister. It was with Zeng. The two men need each other, and they are unmistakably different animals. At a debate in China, Zeng predicted that Tesla's 4680 cell was going to fail. He questioned Musk's grasp of battery production, granted that the American was strong in software and hardware, and noted dryly that Musk tends to promise results on timelines that reality does not honor. It was about as much as a Chinese industrialist can say about a celebrity customer without saying anything at all.
The contrast holds on the page. Asked by the consultancy Roland Berger in September 2025 how CATL was positioning itself amid geopolitical tension, Zeng declined to engage. "I am not in a position to comment on geopolitical tensions," he said. "We simply do business with partners who share our values." It is a remarkable sentence from the chairman of a company the Pentagon had blacklisted eight months earlier. The answer was not evasion so much as jurisdiction. Geopolitics belonged to Beijing. Zeng's territory was chemistry.
The Financial Times's Robin Harding, after interviewing him, wrote that it is always inspiring to meet companies where engineers run the show "and the multi-billionaire proprietor will personally educate you on battery physics." That is the persona Zeng permits himself: not the visionary, not the tycoon, but the lecturer. A man can be very large in physics without appearing too large in politics.
Chemistry Without Loyalty
To understand why CATL keeps winning, it helps to start with a bet that, in hindsight, it was willing to abandon.
In the early years, BYD concentrated on lithium iron phosphate (LFP), a chemistry that is cheaper, safer, and less energy-dense. CATL concentrated on nickel-manganese-cobalt (NMC) ternary cells, which are denser and better for range. At the time, automakers cared most about range. China's subsidy formulas rewarded higher energy density. Zeng read the incentives correctly, and CATL surged past BYD.
Then the incentives changed, and so did CATL.
By 2019, Vivas Kumar, a former manager on Tesla's battery supply chain, was describing CATL as the leader in LFP technology, the chemistry its great rival had championed. In late 2020, CATL began supplying LFP batteries to Tesla for its entry-level car in China. CATL developed cell-to-pack design, which eliminates the intermediate modules inside a battery pack. Pack energy density rose from 140–150 Wh/kg to about 200, the number of parts fell by 40 percent, and production efficiency doubled. That turned the cheaper chemistry from a compromise into a weapon. In 2023 came M3P, which swaps some iron in the LFP formula for magnesium, zinc, and aluminum, raising energy density by 15 percent to 210 Wh/kg. Later that year came Shenxing, an LFP battery that charges from 0 to 80 percent in ten minutes at room temperature. In 2021, CATL unveiled a sodium-ion battery for cars, the first from a major manufacturer, built from a material abundant enough to make lithium politics feel optional. Zeng told Tangen that the second generation of sodium cells would replace 20 to 30 percent of LFP.
This is not a company with a favorite chemistry. Kumar observed that, unlike LG Energy Solution or SK Innovation, CATL is more willing to adopt external technology rather than insisting on purely in-house design. Its loyalty runs to the customer's cost curve, not to its own past. Zeng's description of the business to Tangen was almost comically unromantic: "right chemical, right material," products with "fitness to the purpose of the consumer."
The principle reaches all the way down to the accounting. Zeng depreciates new production lines over five years. His reason, quoted by Mok, is a sentence that would terrify most manufacturing CFOs: "a new chemistry will arrive first." The factory he is building today, he assumes, will be obsolete before it is paid off by conventional standards. So he books it that way, and sunk capital never gets a vote on what the labs do next.
When Tangen asked him who his competitors were, Zeng answered in English, his syntax bent by the effort and somehow clearer for it: "Today, I think the competitor is ourself." He meant it technically. The limit was not LG or Panasonic. It was the cathode materials still in use, LFP and NCM, and the anodes still made of graphite or silicon. "Most important is the new chemistry we have to invent."
He was equally unsentimental about technologies the market loved. In an interview with the Financial Times, he dismissed commercial solid-state batteries as years away. He told Tangen they sat at roughly technology-readiness level four, held back by unresolved science at the solid-solid interface. Instead, CATL was pursuing sodium-ion and "condensed" semi-solid batteries, which the company says store about double the energy of conventional lithium-ion cells. At Summer Davos in June 2024, Zeng reported that a four-ton electric plane had already taken off on condensed batteries, and that CATL was designing for 8.8-ton aircraft with a range beyond 2,000 kilometers.
He made the million-mile claim in June 2020: an electric car battery rated for 1.6 million kilometers. In September 2026 he offered the receipts, a pack still holding 88 percent of its capacity after six years and 840,000 kilometers. In 2024, he noted with what might pass for satisfaction, global lithium battery shipments crossed one terawatt-hour. "I still remember that five years ago, I predicted this milestone would be reached in 2025," he told an industry conference, "but in reality, it came a year earlier."
The ship designer who had once declared car batteries impossible to build had become the man who predicts the industry's volume curves and then beats them.
Dictating the Terms
Scale has a way of changing the grammar of a relationship. In 2012, CATL needed BMW. By 2022, BMW and everyone else needed CATL, and the terms reflected it.
"They're pretty much dictating the terms," Mark Greeven, a professor of innovation and strategy at IMD in Lausanne, told Wired. CATL pushes customers into five-year contracts. It is reluctant to customize batteries for individual carmakers. When raw material prices rise, it passes the increase along. Automakers, Greeven noted, were growing wary of how much power one supplier had over them, and were quietly searching for alternatives.
The supplier's leverage came partly from a structural accident Zeng exploited with total clarity. BYD, his strongest domestic rival, made cars, and so it prioritized battery supply for its own vehicles. That left the world's other automakers looking for a supplier that would not one day compete with them for customers. CATL became that supplier. The list of companies running on its cells reads like the program at an auto show: BMW, Daimler, Hyundai, Honda, Tesla, Toyota, Volkswagen, Volvo, Li Auto, Nio, XPeng, Geely, SAIC. In the first half of 2020, Nio alone accounted for 12.1 percent of CATL's installed volume in China, more than any other customer. That August, CATL co-founded Wuhan Weineng Battery Assets with Nio to finance the startup's battery-swapping model. Being nobody's competitor made it everybody's partner.
The other source of leverage was the mine. Kevin Shang, an analyst on Wood Mackenzie's energy storage team, described how CATL used the profits from batteries "to invest in the whole supply chain, from mining to materials manufacturing to the battery cells making and even to recycling." In April 2021, CATL paid $137.5 million for nearly a quarter of the Kisanfu cobalt deposit in the Democratic Republic of Congo, one of the richest in the world, in partnership with China Molybdenum. It took stakes in nickel in Indonesia. Its recycling operations processed 100,000 tons of spent batteries in 2023 and recovered 13,000 tons of lithium carbonate. In 2024 the figures were 130,000 tons and 17,000 tons of lithium salts. "We are looking for ways to improve the supply chain," Zeng told investors in 2020. That is the sort of thing every chief executive says. Few say it while owning the ground the supply chain starts in.
CATL also began crossing borders physically. It announced a factory in Arnstadt, Thuringia, in 2018, the same year BMW committed to €4 billion of CATL batteries for the electric Mini and the iNext. On August 12, 2022, it announced a plant in Debrecen, Hungary, at €7.34 billion the largest foreign investment in the country's history, to supply Mercedes and BMW. In December 2024 it agreed a €4.1 billion 50-50 joint venture with Stellantis to build an LFP plant in Zaragoza, Spain, with a planned 50 gigawatt-hours of capacity. Meanwhile Northvolt, Europe's homegrown answer, went bankrupt, and Goldman Sachs wrote its $900 million stake down to zero.
In the United States, CATL found a door it could not quite walk through. In 2023, Ford announced a $3.5 billion battery plant in Marshall, Michigan, employing 2,500 workers and licensing CATL's technology. Ford would own the plant, and the domestic production would qualify customers for federal subsidies. Lawmakers objected and the project paused. It continued anyway, and Forbes reports the factory was completed in June 2026. Fortune's editors noticed what had happened to the flow of know-how. Zeng had founded CATL after Beijing forced foreign carmakers to transfer technology to local companies. Now American automakers were the ones licensing Chinese technology to build on American soil. The tech transfer, Fortune wrote, "is now headed in the other direction."
Washington's response escalated year by year. In December 2023, Duke Energy disconnected CATL batteries at Marine Corps Base Camp Lejeune over security concerns. CATL called the espionage allegations "false and misleading." The defense authorization act for fiscal 2024 barred Pentagon funding for CATL products. In June 2024, lawmakers asked the Department of Homeland Security to add CATL to the Uyghur Forced Labor Prevention Act import-ban list. The company called the allegations "groundless and completely false." In August 2024, Marco Rubio and John Moolenaar asked the Pentagon to bar CATL from military contracts. Then came the January 2025 listing, the bank subpoenas, and in January 2026 a Texas order from Governor Greg Abbott banning CATL products from state government devices and networks.
In 2020, before most of this, the U.S. National Advanced Battery Consortium had given Zeng its Lifetime Achievement Award.
Tu Le of Sino Auto Insights summarized the situation bluntly in 2024: the United States was "years behind" China in batteries, and if it wanted to compete globally in electric vehicles through 2030, it would have to use Chinese batteries. Zeng, who had once heard a BMW purchasing manager plead for a supplier, now watched the American government try to plead its way out of needing one.
Version 2.0
Something shifted in Zeng's public voice around 2024. The invisible king started to scold.
The target was not the West. It was his own industry. China's battery and car makers had piled into a price war so intense that it threatened profitability, reputation, and possibly safety. On June 25, 2024, at the World Economic Forum's Summer Davos in Dalian, Zeng joined the critics. "Competition in the [EV] industry should pit players against each other in terms of technology, long-term value, sustainability as well as safety and reliability," he said. "A one-off price competition is not desirable. After all, it is a race throughout the products' life cycle." He argued for a different measure of research effort, absolute spending rather than R&D as a percentage of sales, and gave CATL's figure for 2023: 18.4 billion yuan, about $2.59 billion. He set a defect target of one bad cell in a billion, parts per billion, three orders of magnitude stricter than Six Sigma's one in a million.
On November 20, 2025, at the Gaogong lithium battery conference in Shenzhen, he went further. China produced more than three-quarters of the world's batteries, and Zeng sounded anything but triumphant. He rebuked his peers for homogeneous products, thin research budgets, and a race to the bottom on price at home and abroad. Simply "expanding capacity and earning a bit more money," he warned, could leave the industry unable to carry its share of the energy transition over the next fifteen years. China's battery sector, he said, had to graduate to a "version 2.0" that won something it did not yet have: the world's respect.
A cruder version of the same argument circulated in translation on LinkedIn, and it is worth reading for the moment when the mask slips. Most people entering the battery business, Zeng said, do not start with research. They poach a few people from CATL, lift some technology, scrape formulas off equipment and materials suppliers, bolt it together, and build a factory. Copy the product to 60 or 70 percent and win on price, because procurement managers only watch this year's KPI, and when the battery fails in three to five years, they are long gone. He pointed to solar, where Chinese technology was the best in the world and still did not make money because copying was instantaneous and nobody protected intellectual property. Why hadn't lithium rotted the same way? Because, he said, CATL was holding the price up. Let it fall and the industry would end up worse off than solar. The original Chinese closing line, yao gao si tamen, roughly "sue them to death," was rendered in English as: sue their ass off.
It is the most unguarded sentence on the public record, and it shows something the scripted speeches only hint at. Zeng does not see CATL's pricing power as a reward. He sees it as a duty, the floor that keeps an entire national industry from collapsing into commodity self-destruction. Whether that is industrial statesmanship or a monopolist's self-justification depends on where you are standing. From Ningde it probably looks like both.
On September 3, 2026, he took the argument to its logical end. Speaking by video to the World Power Battery Conference in Yibin, Sichuan, where CATL's plant had been certified in 2022 as the world's first zero-carbon battery factory, he did not talk about energy density or charging speed. He talked about quality. In the first half of the year, China had sold more than 7.4 million new-energy vehicles, almost half of all car sales. Chinese firms held seven of the world's top ten battery spots and more than 70 percent of the market. More than 600 new models had launched domestically that year, nearly three a day, and some batteries had suffered batch failures. Thirty million vehicles worldwide were running on Chinese batteries. At that volume, he said, even a tiny flaw is magnified enormously.
He introduced a phrase, "CATL Quality," defined by three words: safety, reliability, long life. Quality, he said, is not tested into a product. It is designed and manufactured in. Then he described an internal body that is worth pausing on. From its founding, CATL had maintained what he called the industry's only "adversarial group," a multidisciplinary team of electrochemists, mechanical engineers, and AI specialists empowered to hold a veto.
The question for Chinese industry, Zeng said, was no longer whether China could build good electric vehicles. It was whether Chinese brands deserved long-term trust.
— Robin Zeng, World Power Battery Conference, Yibin, September 3, 2026That trust isn't bought with low prices. It comes from high quality, maintained year after year.
The man who once let the regulator drop a nail test was now demanding that his own industry hold itself to a higher standard than the regulator required. These are not contradictions so much as stages. First you survive the rules. Then you write them. Eventually, if you are large enough, you have to live by stricter rules of your own, because your failures now belong to the whole country.
Ningde Era
The headquarters is the most literal building in Chinese industry. It towers over Ningde in the shape of an oversized lithium battery pack, which Wired noted can look to an untrained eye like a giant slide rising out of the sprawl. It is a monument, and monuments in China require permission. A man who cannot be bigger than Beijing can still, it turns out, be bigger than the place he came from, and build that bigness in steel and glass on the hometown skyline.
Ningde's transformation is measurable. Between 2012 and 2021, the city's GDP nearly tripled, and CATL became its largest taxpayer and largest employer. Xinhua turned the city's rise into a case study in "high-quality growth." The municipal government, The New York Times found, locked down access to a wide range of documents, especially from CATL's early days, which means the official version of the story is the only version on file.
The cost of choosing home is also measurable. Talent does not want to live in Ningde. It wants Shenzhen and Shanghai. CATL's answer has been to grow its own and to build pipelines back to the places that once let a village boy in. Zeng has assembled a senior management team of long-serving employees, many of whom grew up in Ningde. On August 19, 2021, he became honorary dean of Shanghai Jiao Tong University's new Future Technology Institute, with CATL's chief manufacturing officer, Professor Ni Jun, as its first dean. That December he gave his alma mater 2 million CATL shares, worth 1.374 billion yuan. On March 31, 2026, his holding company, Xiamen Ruiting Investment, signed over another 5 million A-shares, about 2.0085 billion yuan, to found the Robin Zeng Education Fund, the largest gift in the university's history. Over five years he had given the school that took a shipbuilding student out of Fujian roughly 3.4 billion yuan. His vice chairman Li Ping gave Fudan more than 1.1 billion yuan in shares. Giving is a CATL management discipline too.
Zeng told Tangen that his advice to the young was to strive, be patient, and believe in themselves. He spoke about rural roots and giving back. It would be easy to dismiss this as the Common Prosperity script, and it would be incomplete. A man who leaves a state job after three months, sells his first company, and then buys back the part of it that matters has not lived a patient life. But he has lived a long one in a single industry. "Our team have been working on this industry for now it's a quarter century," he told Tangen, correcting the impression that CATL's twelve-year rise had been sudden. The patience is real. It is just not the patience of someone waiting.
The scale of what got built in the hills around Ningde is hard to convey in numbers, so a cement worker will have to do. In late 2021 CATL was building a factory in Fuding, a ninety-minute drive northeast of downtown Ningde, more than three times the size of Tesla and Panasonic's gigafactory in the Nevada desert. It was one of eight plants under construction at a combined cost of more than $14 billion, with steel-walled buildings fifty feet high and longer than five football fields. A cement worker named Yu Bin told The Times he had recently worked twenty hours straight to finish a roof. "The lights on the cranes," he said, "lit up the night." In August 2026 the company announced that all twenty of its battery plants had been certified carbon neutral, and that it was building an off-grid industrial park powered entirely by wind, solar, and storage to supply a 40-gigawatt-hour battery factory. In Dubai that February, Zeng had compared the moment to humanity's passage from hunting and gathering to agriculture, from tracking down fossil fuels to harvesting energy in wind and solar farms and storing it in batteries.
His net worth was quoted at $63 billion at one point in 2026, $57 billion in July when Forbes China named him the country's best chief executive, and about $48 billion by late September. Fortunes that size fluctuate by more than most companies are worth. He has said he does not want to be the rich guy. Whether or not that is true, it is clear the number is not the thing he is keeping track of.
What he keeps is harder to put on a balance sheet. Each year, when the holidays come and companies around the world send gifts to the customers and partners who matter, CATL, the world's largest battery maker, a company that supplies Tesla and BMW and Toyota and depreciates its factories on the assumption that every chemistry it owns will soon be obsolete, sends fruit: lychees and loquats, grown on the outskirts of Ningde.
Part IIThe Playbook
What follows is an attempt to extract operating principles from Zeng's record. These are not the slogans he offers in Davos keynotes. They are the patterns visible in his decisions: the refusals, the reversals, the purchases, and the silences. Some of them are only available to a founder working inside Chinese state capitalism, and they are noted as such. Most travel further than that. Each principle is grounded in the evidence from Part I and ends with a single tactic.
The principles
- 1.Say no to the big thing, then read every page of it.
- 2.Treat ownership as a political fact, not a financial one.
- 3.Lock the upstream before the downstream exists.
- 4.Be the supplier who will never compete with you.
- 5.Stay loyal to the cost curve, not the chemistry.
- 6.Depreciate faster than the technology does.
- 7.Name yourself as the only competitor.
- 8.Get into the room where the standard is written.
- 9.Never be bigger than your sovereign.
- 10.Use pricing power to hold up the floor.
- 11.Institutionalize the veto.
- 12.Build where you owe something.
Principle 1
Say no to the big thing, then read every page of it
Zeng's first answer to Herbert Diess in 2010 was that car batteries that size were impossible. Within about a year he owned the business that would make them, and when BMW's 800-page requirements arrived, he read them himself, line by line. The refusal and the reading belong together. Both come from an engineer's refusal to accept ambition that has not been specified.
Founders usually hear "say yes to big opportunities." Zeng's record suggests a better sequence. Be honest about what cannot be done with the tools in hand, then do the unglamorous work that changes which tools are in hand. The reading is also a form of leverage. A chairman who knows the customer's specification better than the customer's own engineers negotiates from a very different position.
Tactic: When a transformative customer contract arrives, read its full technical requirements personally before delegating a single page.
Principle 2
Treat ownership as a political fact, not a financial one
Selling ATL to TDK for $100 million in 2005 was rational capital raising. By 2011 it had become a structural handicap: a Japanese-owned company could not become China's battery champion under Beijing's new rules. Zeng's response was to buy 85 percent of the EV business out from under its parent, clear the remaining 15 percent by 2015, exit ATL entirely by 2017, and then publicly stress that CATL was wholly Chinese-owned.
The general lesson is not about China. It is that the nationality, identity, and composition of a cap table determine which markets, subsidies, and regulators will treat you as an insider. Founders tend to evaluate capital by price and terms. Zeng learned, at the cost of a company, to evaluate it by what it would make him in the eyes of the state.
Tactic: Before accepting strategic capital, map which future regulations would treat that investor's nationality or identity as a liability, and price that scenario in.
Principle 3
Lock the upstream before the downstream exists
Within a year of founding CATL, before it had meaningful volume, Zeng set up a subsidiary in Qinghai to secure lithium brine. A decade later he bought nearly a quarter of the Kisanfu cobalt deposit for $137.5 million, took positions in Indonesian nickel, and built a recycling business that recovered 17,000 tons of lithium salts in 2024. As Wood Mackenzie's Kevin Shang described it, battery profits became the funding for the entire chain, from mine to materials to cells to recycling.
The timing is the insight. Raw materials are cheapest, and governments are most eager to see them developed, before your industry gets crowded. By the time competitors realized supply would bind, CATL was the party passing price increases on to its customers. Vertical integration was not an afterthought of scale. It was a precondition for scale.
Tactic: Identify the single input whose scarcity would cap your growth in five years and acquire a position in it now, while you are still small enough to look like a development project.
Principle 4
Be the supplier who will never compete with you
BYD's batteries went first to BYD's cars. That gave every other automaker on Earth a reason to prefer a supplier with no vehicle brand of its own. CATL's customer list, from BMW and Tesla to Toyota, Nio, and Geely, is in part a dividend from that strategic neutrality. In 2020, CATL went further and co-founded a battery-asset company with Nio to finance its swapping model, becoming a partner in the customer's business model rather than just a vendor.
Neutrality compounds. Each new customer makes the supplier more central and therefore more attractive to the next one. The cost is discipline: you must resist the temptation to move downstream even when the margins there look attractive. Zeng has built chassis, swap stations, and grid systems, but never a car brand competing for the driveway.
Tactic: Write down the downstream markets you will never enter, and make that commitment visible to the customers who most fear you would.
Principle 5
Stay loyal to the cost curve, not the chemistry
CATL won its first decade on NMC ternary cells, because range was what automakers wanted and energy density was what subsidies rewarded. Then it became the world leader in LFP, the chemistry its rival had championed, and supplied it to Tesla from 2020. Then it pushed sodium-ion, M3P, and condensed semi-solid cells, while publicly dismissing solid-state as years away. Former Tesla supply-chain manager Vivas Kumar observed that CATL adopts external technology more readily than rivals committed to pure in-house design.
⚗
A Portfolio of Chemistries
How CATL positions its technologies by readiness and role, based on public statements and launches.
| Technology | Role in the portfolio | Stage |
|---|---|---|
| NMC ternary cells | Won the early range race and the subsidy formula | Scale |
| LFP with cell-to-pack, M3P, Shenxing | Turned the cheaper chemistry into the volume weapon; Tesla supply from 2020 | Scale |
| Sodium-ion | Unveiled 2021; second generation expected to displace 20–30% of LFP | Try |
| Condensed semi-solid | Roughly double energy density; four-ton electric aircraft already flown | Scan |
| All-solid-state | Publicly judged years from commercialization, around TRL 4 | Risk |
A technology company that falls in love with its own architecture becomes a hostage to it. Zeng's phrase for what he sells, "right chemical, right material," with "fitness to the purpose of the consumer," is deliberately unromantic. Strategy follows the customer's total cost and the regulator's incentives, wherever they lead in the periodic table.
Tactic: Maintain at least one serious program in the technology that would most threaten your current flagship, and staff it as if you expect it to win.
Principle 6
Depreciate faster than the technology does
Zeng writes off new production lines over five years because, in his words, "a new chemistry will arrive first." The accounting choice is really a cultural one. A factory that is already carried at a low value on the books cannot argue for its own survival when the lab produces something better. Sunk cost loses its political weight inside the company.
Most manufacturers set depreciation schedules to flatter near-term earnings. Zeng uses them to protect the future from the present. The cost is lower reported profit in the early years of a line. The benefit is an organization that never hesitates to replace its own products.
Tactic: Set the useful-life assumptions on your core assets to match the realistic arrival of the next generation, not the physical life of the equipment.
Principle 7
Name yourself as the only competitor
Asked by Nicolai Tangen who CATL's competitors were, Zeng said, "Today, I think the competitor is ourself." He then refused to call rivals competitors at all. He said he welcomed more inventors into the industry, as long as they were not copycats. At 37.5 percent global share, this sounds like arrogance. In practice it redirects the organization's attention from market share to the limits of the science: graphite anodes, cold-weather performance, chemistries not yet invented.
The framing also explains his fury at imitators. Inventors expand the frontier. Copycats, in Zeng's account, take 60 to 70 percent of the technology, compete on price, and leave failures for customers to discover three to five years later. His distinction is between rivals who make the industry better and rivals who make it cheaper, and he treats only the first as legitimate.
Tactic: Replace competitor benchmarking in your strategy reviews with a list of the technical limits your own product has not yet broken.
Principle 8
Get into the room where the standard is written
When BYD's nail-test video threatened CATL's chemistry in 2020, the regulation that replaced the test listed CATL first among its drafters, ahead of the government's own testing agency. The case is extreme and specific to China. The underlying principle is universal in regulated industries: the company that helps write the standard gets to define what "safe" and "compliant" mean, usually in terms that fit its own architecture.

2025
Added to the Pentagon's "Chinese military companies" list in January; largest IPO of the year in Hong Kong in May.
The ethical line is real, and so is the risk: the same proximity that wrote the nail-test rule now fuels American suspicion of the company. But a founder who leaves standards to others leaves the definition of the market to others.
Tactic: Assign a senior technical leader to every standards body that governs your product, with the mandate to draft language rather than merely comment on it.
Principle 9
Never be bigger than your sovereign
"You can't be bigger than Beijing," Bill Russo said, and Zeng's career reads like a commentary on that sentence. He rarely gives interviews. He echoes official framing on climate and common prosperity. He serves on the CPPCC. He declines to discuss geopolitics even while his company is blacklisted. When he does speak, he speaks as a physicist and lecturer, not as a visionary.
The broader lesson applies anywhere a company's fate depends on a power larger than itself: a dominant platform, a sole regulator, a single anchor customer. Visibility is a resource that can be spent. Zeng spends it narrowly, on product claims, industry discipline, and quality, and never on personal mythology. The contrast with Musk, whom he quietly criticized over the 4680 cell and unrealistic deadlines, is the point.
◐
Two Models of the Industrial Founder
Where Zeng's public conduct departs from the Western founder playbook.
| Conventional wisdom | Zeng's approach |
|---|---|
| Build a personal brand as the face of the mission. | Stay invisible; let the product and the hometown carry the name. |
| Have opinions on everything. | "I am not in a position to comment on geopolitical tensions." |
| Promise aggressive timelines to rally capital. | Dismiss hyped technologies; predict industry volumes, then beat them. |
| Celebrate wealth as a scoreboard. | "I don't want to be the rich guy." |
| Pick a technology and evangelize it. | Treat every chemistry as provisional, including your own. |
Tactic: Identify the single power your business cannot survive offending, and audit every public statement you make for whether it competes with that power for attention.
Principle 10
Use pricing power to hold up the floor
The most surprising thing Zeng has said is that CATL deliberately keeps prices up, not only for its own margins but because a price collapse would leave the lithium battery industry "worse off than solar," where the world's best technology earns no money. His public campaign against price wars, from Summer Davos in 2024 to the Gaogong conference in 2025, rests on one claim: competition should run "throughout the products' life cycle," measured in cost per cycle and years of service, not sticker price.
A market leader can either race competitors down or anchor the market at a level that funds research. Zeng chooses to anchor, and he justifies the choice with lifecycle economics, citing a pack at 88 percent capacity after 840,000 kilometers and a storage project still above 80 percent after nine years. Leaders who join the race to the bottom usually end up at the bottom with everyone else.
Tactic: Reframe your pricing around total cost of ownership over the product's life, and publish the durability data that makes the higher upfront price defensible.
Principle 11
Institutionalize the veto
CATL has kept, from its founding, what Zeng calls the industry's only "adversarial group": electrochemists, mechanical engineers, and AI specialists with the power to block products. He pairs it with a parts-per-billion defect target and the conviction that "quality is not tested into a product, but designed and manufactured into it."
Large companies tend to suppress internal dissent precisely when they can least afford to, at scale, when a small defect multiplied across thirty million vehicles becomes a national embarrassment. A standing adversarial body with real authority turns skepticism from a career risk into a job description. It is also the institutional form of the founder who once told BMW that something was impossible.
Tactic: Create a small, cross-disciplinary team whose only job is to find reasons a product should not ship, and give it binding veto power over launches.
Principle 12
Build where you owe something
Zeng put CATL in Ningde, a city recruiters regard as a backwater, and named it after the place: the Ningde Era. The costs are real, chiefly talent. The returns are less visible but durable. CATL is the city's largest employer and taxpayer, it enjoys local political goodwill that is hard to replicate, and its senior team is made up of long-serving executives, many from Ningde, whose loyalty is not for sale in Shenzhen. Zeng has paid down the talent gap from the other end, giving roughly 3.4 billion yuan to Shanghai Jiao Tong University and lending CATL's manufacturing chief to found its Future Technology Institute.
Rootedness is unfashionable in a world of remote teams and tax-optimized domiciles. Zeng's record suggests that a company embedded in a place that depends on it gains a constituency that defends it, and a culture with a reason to exist beyond the next quarter.
Tactic: Locate at least one core operation where your company would be the most important employer, and invest in the education pipelines that will staff it for a generation.

— Robin Zeng, Summer Davos, Dalian, June 25, 2024A one-off price competition is not desirable. After all, it is a race throughout the products' life cycle.
— Robin Zeng, interview with Roland Berger, September 2025I am not in a position to comment on geopolitical tensions. We simply do business with partners who share our values.

Maxims
- Refuse honestly. "Impossible" with today's tools is the beginning of a plan, not the end of a conversation.
- Read the spec yourself. The founder who knows all 800 pages negotiates from a stronger position than the one who knows the summary.
- Ownership is jurisdiction. Who owns you decides which markets will treat you as one of their own.
- Buy the mine early. Secure the scarce input while your industry still looks like a development project.
- Compete with no customer. Neutrality is what earns a supplier a place in every competitor's supply chain.
- No favorite chemistry. Stay loyal to the customer's cost curve, and let your own past bets lose.
- Write off the present. Depreciate assets on the schedule of the next breakthrough, not the life of the machine.
- Stay smaller than the sovereign. Spend visibility on the product, never on the persona.
- Hold the floor. Pricing power used to end a race to the bottom funds the research that keeps you ahead.
- Give the skeptics a veto. At scale, the people who say no are the ones protecting the brand.
