How did a kid from a small mountain village in Fujian end up building the company that powers one in every three electric vehicles on the planet? This episode explores the rise of CATL (aka the “TSMC of batteries”) and its founder, Robin Zeng.

It begins with CATL’s predecessor, ATL, and a risky $1 million bet on a flawed battery patent that nearly destroyed the company — until it unexpectedly led to a breakthrough deal supplying Apple iPods.

CATL was later spun out amid government policy shifts and EV subsidies, and scaled into the world’s largest battery maker in just six years. Its first major test came with BMW, where passing an 800-page technical audit proved it could meet strict automotive standards—unlocking global partnerships.

Today, CATL continues to push its limits, expanding into grid-scale energy storage, aviation batteries, and next-generation technologies like sodium-ion and solid-state systems to stay ahead in the global energy race.
