Back in the early nineties, when community firefighters gained a phone from Moli Power, they knew accurately where to head: the company’s battery warehouse. The Vancouver-based mostly business was the initially to mass develop rechargeable lithium-metallic batteries. But the batteries had a unpleasant behavior of exploding, which finally led to a enormous remember that bankrupted the business.
Thirty many years have passed, but today’s lithium-ion batteries are still wont to blow up. One offender is the liquid electrolyte, a generally flammable natural and organic solvent that facilitates the movement of ions between a battery’s electrodes. Replacing this flamable materials with a solid, some argue, could develop safer batteries.
The fact, nevertheless, is never as very simple. Stable-condition electrolytes, even though absolutely much less flammable than their liquid counterparts, are not entirely immune to fires both. But that could now alter, many thanks to new technology made by a team led by Yi Cui, a materials scientist at Stanford University.
