Batteries that don’t burn

July 18, 2025

Batteries that don’t burn: Lithium batteries are super efficient and occasionally super explode-y. But researchers just made a version that stops itself from catching fire. When the battery gets too hot, built-in flame retardants release chemicals that shut down the reaction before it becomes a fireworks show. No flames. No smoke. No 30,000-gallon fire truck cameo. EVs really need this pronto.
