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

Back in the early nineteen nineties, when community firefighters received a get in touch with from Moli Strength, they understood specifically where to head: the company’s battery warehouse. The Vancouver-dependent organization was the initial to mass produce rechargeable lithium-metal batteries. But the batteries had a unpleasant behavior of exploding, which finally led to a massive recall that bankrupted the organization.

30 decades have handed, but today’s lithium-ion batteries are even now wont to blow up. 1 perpetrator is the liquid electrolyte, a commonly flammable natural and organic solvent that facilitates the flow of ions amongst a battery’s electrodes. Replacing this flamable materials with a reliable, some argue, could produce safer batteries. 

The fact, however, is never as easy. Reliable-condition electrolytes, when certainly significantly less flammable than their liquid counterparts, are not solely immune to fires either. But that could now alter, many thanks to new technologies formulated by a workforce led by Yi Cui, a products scientist at Stanford College.
