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

Back in the early 1990s, when local firefighters been given a simply call from Moli Electricity, they knew particularly the place to head: the company’s battery warehouse. The Vancouver-centered organization was the initially to mass develop rechargeable lithium-metal batteries. But the batteries had a unpleasant pattern of exploding, which eventually led to a enormous remember that bankrupted the organization.

Thirty many years have handed, but today’s lithium-ion batteries are continue to wont to blow up. Just one offender is the liquid electrolyte, a typically flammable natural and organic solvent that facilitates the stream of ions in between a battery’s electrodes. Replacing this flamable material with a stable, some argue, could develop safer batteries. 

The truth, even so, is never ever as very simple. Sound-point out electrolytes, even though absolutely considerably less flammable than their liquid counterparts, are not fully immune to fires both. But that could now transform, many thanks to new engineering designed by a staff led by Yi Cui, a materials scientist at Stanford University.
