A Lithium-Ion Battery That Works Even When It’s on Fire

Again in the early nineties, when regional firefighters gained a connect with from Moli Electricity, they knew precisely where to head: the company’s battery warehouse. The Vancouver-dependent business was the 1st to mass make rechargeable lithium-metallic batteries. But the batteries experienced a nasty behavior of exploding, which sooner or later led to a substantial remember that bankrupted the business.

30 yrs have handed, but today’s lithium-ion batteries are continue to wont to blow up. A single perpetrator is the liquid electrolyte, a normally flammable natural solvent that facilitates the flow of ions in between a battery’s electrodes. Changing this combustible materials with a strong, some argue, could make safer batteries. 

The actuality, nevertheless, is under no circumstances as simple. Good-condition electrolytes, whilst definitely fewer flammable than their liquid counterparts, aren’t solely immune to fires either. But that could now change, thanks to new technology made by a staff led by Yi Cui, a components scientist at Stanford College.
