As electric vehicles (EVs) become more powerful and widespread, thermal runaway remains one of the industry’s most pressing safety challenges. This chain reaction, where a single overheating battery cell can trigger fires in adjacent cells, has led to high-profile incidents and increasingly strict global safety regulations. Countries like China, India, and members of the EU are now mandating systems that can delay or even prevent thermal propagation within EV battery packs.
