This means CATL’s battery cannot catch fire or explode within two hours of an accident in most cases.

This is a significant improvement on the five minutes specified in a current version of China’s safety rules dating from 2020. The new requirements were drafted by dozens of entities including CATL, CATARC, and BYD. International automakers including Tesla, Toyota, and Volkswagen were also involved.
