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

Again in the early 1990s, when regional firefighters obtained a simply call from Moli Vitality, they knew specifically wherever to head: the company’s battery warehouse. The Vancouver-dependent organization was the to start with to mass create rechargeable lithium-steel batteries. But the batteries had a horrible behavior of exploding, which finally led to a enormous recall that bankrupted the organization.

30 many years have handed, but today’s lithium-ion batteries are nonetheless wont to blow up. One particular culprit is the liquid electrolyte, a generally flammable organic solvent that facilitates the circulation of ions concerning a battery’s electrodes. Changing this combustible substance with a sound, some argue, could create safer batteries. 

The actuality, even so, is hardly ever as easy. Good-point out electrolytes, whilst unquestionably much less flammable than their liquid counterparts, aren’t entirely immune to fires possibly. But that could now change, many thanks to new engineering produced by a team led by Yi Cui, a resources scientist at Stanford College.
