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

Back again in the early nineteen nineties, when local firefighters been given a contact from Moli Power, they realized precisely wherever to head: the company’s battery warehouse. The Vancouver-based mostly business was the to start with to mass generate rechargeable lithium-metallic batteries. But the batteries experienced a terrible pattern of exploding, which ultimately led to a massive recall that bankrupted the business.

Thirty yrs have passed, but today’s lithium-ion batteries are nonetheless wont to blow up. A person culprit is the liquid electrolyte, a typically flammable natural and organic solvent that facilitates the movement of ions involving a battery’s electrodes. Changing this flamable material with a strong, some argue, could generate safer batteries. 

The reality, on the other hand, is never ever as easy. Sound-condition electrolytes, while absolutely a lot less flammable than their liquid counterparts, aren’t completely immune to fires possibly. But that could now change, thanks to new technological innovation developed by a group led by Yi Cui, a components scientist at Stanford College.
