Zeng worked at a state-owned shipbuilding company in Fujian Province early in his career. He later joined an electronic parts factory after graduation where he worked for 10 years. He then co-founded
Amperex Technology Limited (ATL) in 1999 with two former colleagues. The company produced
lithium polymer batteries for digital gadgets, including iPhones, according to a Financial Times report in 2018. In 2005, ATL was acquired by Japan's
TDK, but Zeng continued as a manager for ATL. In 2012, Zeng and vice-chairman
Huang Shilin spun-off the
electric vehicle battery operations of ATL into a new company CATL, which manufactures lithium-ion rechargeable batteries, and became a world leader in the following years. In 2017, CATL went public on the
Shenzhen Stock Exchange. == References ==
