There is one company in Colorado making Li-S batteries at small scale: http://www.solidpowerbattery.com/ http://www.solidpowerbattery.com/
- hwillis 9y agoLiS8 + silicon batteries would be a dream: immediate 8x boost in capacity for a given weight and the size is halved. Unfortunately the damn thing tries to swell to 200% size when you charge it and lasts for six cycles. Someone may figure out how to make it work but most likely itll use nanotech (like a123 did with FePO4, or a graphene coating). The fact is its such a hard problem there are very few ways it could be done cheaply. Right now LiS is only applicable to very, very niche applications. SolarImpulse used them. They come at a very high price and limited longevity.
