The founder of China’s world-beating battery manufacturer is pressing ahead with expansion in the face of a global slowdown in electric-vehicle sales growth.

Contemporary Amperex Technology Co. Ltd. isn’t worried about overcapacity, and in fact will crank up output of its more technologically advanced products, said Robin Zeng, president and chairman of the company better known as CATL. In his first interview with an international news outlet since 2020, he said his company has found the solutions to get battery-charge times down to 10 minutes, and is working on reducing them even further.
