From a single factory in this coastal Fujian city, a once-obscure battery maker has become the linchpin of the global electric-vehicle industry. Contemporary Amperex Technology Co., Limited, known as CATL, now controls more than a third of the world’s EV battery market, a dominance built over little more than a decade by its founder and chairman, Zeng Yuqun.
In the West, he is often called Robin Zeng. Zeng’s ascent mirrors China’s broader push to lead in electric vehicles and advanced manufacturing. By 2017, just six years after CATL was spun off from an earlier battery venture, the company had overtaken all rivals to claim the top global market share — a position it has held ever since.
The scale of that lead is stark: according to SNE Research, CATL held 37 percent of the global EV battery market in 2023. The company’s revenue that year reached $48 billion, with net income of $6.5 billion.
Zeng himself became China’s richest person in 2023, with Forbes estimating his net worth at $45 billion.
From Consumer Electronics to Electric Vehicles
Zeng’s path to battery supremacy began in 1999, when he founded Amperex Technology Limited, or ATL, a supplier of lithium-ion batteries for consumer electronics. ATL grew into a major player in that market, but its trajectory shifted when Japan’s TDK acquired the company in 2005. Zeng remained involved, and in 2011 a group of investors led by him spun off the EV battery division into a new company, CATL.
TDK retained a minority stake until 2015. CATL’s rise coincided with China’s strategic push to develop its domestic electric-vehicle industry, including subsidies and policies that encouraged technology transfer from foreign automakers.
The company began supplying BMW Brilliance in 2012 and quickly expanded its reach to other global carmakers. Today, CATL’s customer list includes Tesla, BMW, Volkswagen, Mercedes-Benz, Hyundai, and numerous Chinese automakers. The company leveraged China’s control over key battery materials and supply chains to cement its position.
The sheer scale of production is enormous: CATL had a production capacity of 250 gigawatt-hours as of 2023, with plans to expand to 800 GWh by 2025. That capacity positions the company to meet a significant portion of global demand as the auto industry accelerates its shift to electrification.
Key Innovations and Geopolitical Headwinds
Zeng, born in 1968 in Ningde, holds a Ph.D. from the Institute of Physics, Chinese Academy of Sciences, earned in 1993. His technical background has shaped CATL’s research strategy.
In 2021, the company introduced sodium-ion batteries, a technology designed to reduce reliance on lithium, a commodity subject to price volatility and supply constraints. The following year, CATL launched the Qilin battery, which the company stated offers up to 1,000 kilometers of driving range on a single charge — a benchmark that could help ease consumer range anxiety and further drive EV adoption. Despite its commercial success, CATL has faced scrutiny in Washington.
The company has encountered concerns over potential U.S. sanctions due to its ties to the Chinese military, though CATL has denied any military connections. These geopolitical headwinds underscore the delicate position of a firm that is both a critical supplier to Western automakers and a symbol of China’s growing influence in advanced manufacturing.
Zeng has kept a relatively low public profile even as his company has become a cornerstone of the global energy transition. CATL’s growth reflects broader shifts in the global auto industry toward electrification, as well as China’s expanding role in the supply chains that underpin that transition. The company’s innovations in sodium-ion and high-range batteries have further cemented its role in shaping the future of transportation and energy storage. Yet the same government policies that fueled CATL’s rise also created the conditions for the geopolitical tensions that now shadow its operations.
As the world’s largest EV battery maker, CATL occupies a position of both immense opportunity and considerable risk.
