Tesla needs to succeed in China if it wants to dominate the world of electric cars , especially in a post-coronavirus world. To do that, Elon Musk is turning to a battery engineer who once helped Apple extend the life of its MacBook laptops. Zeng Yuqun, 52, built Contemporary Amperex Technology Co Ltd. (CATL) into China’s battery champion in less than a decade, creating the largest global producer of rechargeable cells for the plug-in vehicles considered to be the future of cars. That effort has helped propel Zeng from a modest hillside village and US$30-a-month job with a state-run company to an estimated US$17 billion (HK$131.7 billion) fortune. CATL’s products are in almost every major global auto brand, and starting this month they’ll also power electric vehicles manufactured by Tesla at its new factory on the outskirts of Shanghai. It is an alliance with lucrative potential, combining the sector’s most-popular car – the Tesla Model 3 – with low-cost batteries in a sizeable market . Last year, Chinese consumers bought more than three electric vehicles for every one sold in the US, but faces an uncertain future as the pandemic rocks the global economy. There is already a developing partnership between the two executives, according to Zeng. The pair trade text messages to discuss prospective innovations in technology, their responses to the challenges wrought by the coronavirus and the Tesla chief’s primary obsession: cheaper batteries and vehicles. “Elon talks about cost all day long, and I told him to be assured that I would have solutions,” Zeng said in an interview at CATL’s headquarters in Ningde, where his 20th-floor office overlooks a fishing hub on China’s southeastern coast now transformed by clusters of battery plants and laboratories. “We get along well. He’s a fun guy.” CATL’s batteries can offer the Palo Alto, California-based company key advantages in China, particularly the potential to boost margins and lower sticker prices in a market on track to have 59 million EVs on the road by 2030. Most importantly, Zeng is expected to supply Tesla with lithium-iron-phosphate (LFP) batteries that use a cheaper mix of raw materials and cost about 20 per cent less to make than other common types of packs, according to BloombergNEF. CATL confirmed in a February filing it would become a supplier to Tesla, but both declined to disclose precise details, including the types of packs involved. Working with a domestic supplier like CATL could further burnish Tesla’s relations with China’s authorities, which have been key to its local success. What’s more, Zeng serves on the Chinese People’s Political Consultative Conference, the advisory body to top leadership. There, he is put forward proposals to further focus on renewable energy. For CATL, the alliance comes at a crucial time. Battery sales fell almost a third in the first five months of 2020, according to SNE Research, as car purchases plunged in China amid the pandemic, trade war and a scaling back of government subsidies. Electric-car sales have declined about 38 per cent from a year ago , the China Association of Automobile Manufacturers said July 10, and that risks exposing the country’s multibillion-dollar EV push as a bubble. The battery producer’s domestic market share also ebbed as Tesla rolled out its first China-made Model 3s with batteries from LG Chem and Panasonic. Starting next year, CATL should supply components for about half the Shanghai plant’s output, according to broker Sanford C. Bernstein. Tesla’s China plant might have come to the carmaker’s rescue last quarter Aligning with Tesla will boost domestic sales, though CATL also needs to secure additional clients to improve its prospects outside China, where LG Chem and Samsung SDI, among others, are positioning themselves at a rapid pace. The battery supplier has an eye on extending links with Tesla overseas, including to the automaker’s first European factory under construction outside Berlin. CATL, which also supplies Volkswagen and BMW, is building its own facility in central Germany and encouraging China-based suppliers to set up outposts there. “We will not exclude the possibility to supply its Berlin Gigafactory,” Zeng said in the interview. Tesla did not respond to requests for comment. Zeng has delivered in the past for blue-chip partners. His team helped BMW’s China joint venture develop its early battery-powered models, and CATL now has an 11-year supply contract with the German parent. At CATL’s forerunner company, Zeng helped Apple deliver long-life batteries for the MacBook Air. The supplier now sees an advantage in accelerating research on lower battery costs to help electric-powered cars achieve price parity with, and subsequently supplant, gas guzzlers. “You have to be more innovative, more cost-efficient, with better performance,” Zeng said. “That is the only way to beat them.” CATL is poised to commercialise new types of batteries made without cobalt, among the most-expensive raw materials. Beyond that, it wants to eliminate other costly metals, such as nickel and manganese. According to Zeng, the supplier also is capable of producing a long-life battery that lasts 16 years and 2 million kilometres (1.24 million miles), and is intended for use in multiple vehicles and in energy storage. That is a milestone others, including Tesla and General Motors, are chasing. More research facilities are under construction in Ningde, where entire city blocks are filled with laboratories and flat for CATL staff. They include the “Cloud-Capped Pavilion” neighbourhood where Zeng and his wife have a top-floor home. A 3.3 billion-yuan (US$470 million) research-and-development complex is intended to be a global flagship. “Incremental improvements can build a well-performing company, but not a great one,” said Zeng. A sand model of the planned centre sits on the floor by his office door. “We invest in geniuses.” Zeng himself earned a doctorate in condensed matter physics from the Chinese Academy of Sciences in Beijing. Spending by CATL on R&D jumped about 50 per cent last year, to almost 3 billion yuan, and the firm has almost 5,400 staff focused on the tasks. They include 143 workers with doctorate degrees – who receive such perks as their own canteen and can take advantage of a company-run dating service that took credit for 52 marriages last year. Even before the new research hub, CATL’s efforts put it among the top tier of the industry, said Hu Feng, a partner at Shenzhen-based Gao Gong Lithium Battery Research Center, who has tracked Zeng’s work for almost a decade. The sophisticated labs and new factories coming in China and Germany are a marked contrast to the makeshift production lines of Zeng’s early career. Staff members coated batteries with a paint brush in one hand and a hairdryer in the other, and Zeng once used paper clips as a temporary fix to stop vibrating equipment from damaging cells. Now, staff don medical-style protective clothing to limit the spread of dust before passing through a high-pressure air shower. In a nearby lab, batteries are shaken, crushed, immersed in water for 48 hours and placed into boxes heated to 130 degrees Celsius (266 degrees Fahrenheit). “What we do is try to bring innovations to the structure and chemical system, which will enable Tesla cars to drive a longer range at a better cost,” said Zeng. “That is probably why Tesla likes us.” By using CATL’s cheaper and smaller batteries for the Model 3, Tesla’s costs per car could fall between US$600 and US$1,200, according to Bernstein. LFP packs traditionally haven’t been as powerful as more expensive alternatives, yet the technology is catching up. “It could be pretty explosive if they get that in the international market because no one else is using LFP outside China in pure EVs,” said Mark Newman, a Hong Kong-based senior analyst at Bernstein. “Tesla would have a pretty meaningful advantage.”
