The new assembly lines would quintuple CATL's production capability and make it the world's largest electric-vehicle battery cell manufacturer, ahead of Tesla, Warren Buffett-backed BYD, in China and South Korea's LG Chem, according to Bloomberg New Energy Finance.

The factory could go fully online as soon as 2020, an opportune time as China targets a sevenfold increase in new-energy vehicle sales by 2025 and ponders a course for phasing out fossil-fuel vehicles altogether.

"China, unabashedly, wants to be the Detroit of electric vehicles," said Anthony Milewski, a managing director at Pala Investments, a Switzerland-based fund investing in the EV supply chain. "There is no question in my mind that they are going to lead the world in capacity and, eventually, in the technology."

China's government likes to have national champions of industry: think Alibaba Group in e-commerce and Tencent Holdings in social media. So far no car makers are part of that conversation, although CATL is working its way in there by capitalising on China's push for cleaner air and fewer oil imports. The rising battery giant is, in no small part, a manifestation of China's aggressive government support for electric vehicles.

China surpassed the US in 2015 to become the world's biggest market for electric cars. Sales of new-energy vehicles-including battery-powered, plug-in hybrid and fuel-cell vehicles-reached 777,000 units last year and could surpass 1 million this year, the China Association of Automobile Manufacturers estimated.

In China, the source of 99 per cent of CATL's business, the company's lithium-ion batteries will be inside locally made EVs from Volkswagen, BMW, and Hyundai. Japan's Toyota, Honda and Nissan are considering CATL batteries for planned China-made vehicles. Domestic companies using the batteries include BAIC Motor, the biggest EV seller in China, and Zhengzhou Yutong, the world's biggest bus maker.

CATL is already in the midst of expanding overseas. Last year, it spent €30 million ($46.6 million) to acquire 22 per cent of Finland's Valmet Automotive Oy, a contract manufacturer for Daimler AG's Mercedes-Benz and supplier to Porsche and Volkswagen's Lamborghini. CATL also added offices in Paris to existing facilities across Germany. The company has a partnership with BMW's motorsport teams for races in Europe and Macau, splashing its blue logo across the car maker's M6 GT3.

Now CATL is making another leap. Job ads for positions in the Detroit area have appeared on LinkedIn, and the company said in an email it is meeting with several US car makers to discuss partnerships.


"Their intentions are very clear," said Simon Moores, London-based managing director of battery sector consultant Benchmark Mineral Intelligence. "To not just be China's biggest battery producer but the world's largest."

Ningde doesn't look like a global foundry for the key technology inside the cars of the future. The isolated city is surrounded by mountains, with a long history of fishing and farming that has more recently made way for a few Starbucks and McDonald's locations. President Xi Jinping apprenticed there as a Communist Party chief in the 1980s, when Ningde was the poorest city on China's east coast.

Menahem Anderman, president of Total Battery Consulting in Petaluma, California, went to see CATL's headquarters for himself in January and found a company in the process of becoming a world-class battery maker. "Technically they are a probably a tad behind the big three," he said, citing Panasonic, Samsung SDI, and LG Chem. "But considering how fast they have been moving, it's reasonable to assume that in two to three years they'll have a technically similar product."

The new battery plant is set to rise on landfilled mudflats across a lake from CATL's sprawling headquarters. The entire complex, all barely seven years old, is vast enough that it takes half an hour to walk from an office building on the northwest corner to a gate on the east side. Six electric shuttle buses, all powered by CATL batteries, trundle employees between dormitories, factories and research labs. For the 90-minute trip to the nearest airport in Fuzhou, employees can book free chauffeured rides in a Zinoro hybrid built by BMW's joint venture and powered by CATL batteries.

Zeng Yuqun, the 49-year-old engineer who founded CATL, is often seen walking fast across the campus. He was born in a mountain village an hour away and sometimes organises employee excursions to his birthplace. For most of his career, he worked on lithium-ion batteries for consumer electronics, including the iPhone, at Amperex Technology, a subsidiary of Japan's TDK that he helped found.

Zeng's decision to start CATL in 2011, while he was president of ATL, marked a gamble on the direction of Chinese government policy. That year there were just 1014 alternative-energy vehicles sold in China, according to Bloomberg Intelligence. He was essentially betting that the lithium-ion battery business for cars would flourish, creating a replica of ATL focused on a vehicle market that barely existed.

Zeng's prediction proved right: Xi's administration now provides generous incentives for consumers buying non-gasoline vehicles. In 2016 and 2017, those subsidies may have totalled 83 billion yuan, according to an estimate from Cui Dongshu, secretary-general of the China Passenger Car Association.

Car makers seeking to qualify choose domestic battery suppliers because of concerns that models built with foreign brands will be ineligible, even though there isn't a written rule banning non-Chinese suppliers. "The premise is that locally produced cars in China are obligated to use local batteries," Jochem Heizmann, chief executive of Volkswagen Group China said in January.


Zeng, who declined to comment for this article, can be blunt about the electric-vehicle business. During a forum in China last year, he made it clear that he doesn't see himself in competition with other battery supplies. "We are competing with gasoline cars," he said. "If we can't win against gasoline cars, there's no place for us in the market."

If CATL made itself into an emerging battery giant on the strength of Chinese policy, Zeng already appears worried about securing a future without that help. In April, he sent an internal email meant to motivate his employees. The title of his letter posed a question: "When the typhoon comes, can pigs really fly?"

Zeng proceeded to use an allegory to caution workers against complacency. "Is the pig really flying? What happened to the pig after the typhoon is gone?" he wrote, according to the company's WeChat account. The pig is the company, the strong winds are government subsidies, and the danger is that favourable policies won't always be there to provide uplift.

CATL reaps further benefits from an aggressive government policy to acquire the minerals needed for battery makers. China is securing supplies of key materials such as lithium, nickel and rare earths, and its mining companies are estimated to be responsible for 62 per cent of the global supply of cobalt, the Cleveland-based Institute for Energy Economics and Financial Analysis said in a January report.

The upcoming IPO should propel CATL to become the biggest lithium-ion battery cell maker in the world. The company previously forecast sales of as much as 100 billion yuan by 2020, a huge jump from 14.9 billion yuan in its last full-year earnings from 2016. The company's ramp-up, in turn, will extend China's grip on global battery production to about 70 per cent of the market by 2021, up from 54 per cent last year, according to BNEF.

That startling growth has some overseas origins. "Their technological background and procedures are quite good, partly because they have some history with a Japanese company," said Mark Newman, a senior research analyst with Sanford C Bernstein in Hong Kong.

There's also German engineering in its DNA. In 2011, CATL was chosen by BMW and local partner Brilliance China Automotive to supply their domestic premium EV brand, Zinoro.

Last year, the German car maker hosted a coming-out party for its plug-in hybrid model, the 60H, amid coconut trees on the resort island of Hainan. Johann Wieland, president of the Chinese joint venture, and Zeng stood side-by-side to pose for photos with the silver model.


"We have learned a lot from BMW, and now we have become one of the top battery manufacturers globally," Zeng said at the event. "The high standards and demands from BMW have helped us to grow fast."

Helping power the growth is a strong research-and-development effort, said Zhou Lei, a Tokyo-based partner covering the auto industry for Deloitte Tohmatsu Consulting. CATL has ties to institutes in Germany and State College, Pennsylvania, according to its website.

CATL spent 670 million yuan on research during the first half of last year, or about 11 per cent of revenue, according to its prospectus. BYD, China's largest maker of NEVs, spent 2.76 billion yuan, or 6 per cent of revenue, according to the company.

Research-and-development staff comprise a fifth of CATL's 18,000-plus workforce, and the company plans to use 4.2 billion yuan from the IPO to develop next-generation batteries, it said.

When completed, the new 24 gigawatt-hour factory will catapult CATL to the top of the manufacturing capacity rankings. Currently, it has 17.5 gigawatt hours a year in capacity either in operation or about to come online. A gigawatt hour is the equivalent of 1 million kilowatt hours of electricity-about enough to power 1 million homes for an hour.

The factory will boost that total to 41.5 gigawatt hours, surpassing LG Chem's production, BNEF said in a November report. By comparison, Tesla's Gigafactory will have a capacity for 35 gigawatt hours.

"Their ambitions are 100 per cent global, and I believe they are going to be global competitors," said Pala Investments' Milewski. "You have the Chinese government behind them, and you have some of the smartest people in the world working there."
