None of the majors have.VW haven't been great at picking the best bets...
I am not putting Quantumscape forward because of their VW connection. Quantumscape have an interesting ceramic separator that makes solid lithium anodes possible.
If it pans out which so far looks possible, it will be a real game changer. The financial backing from VW is important from an economic sustainability point of view and for testing and validation.
I followed quantumscape since they came out of hiding and followed them as closely as possible. Although I am sceptical of solid state batteries, these guys are at the stage of pre-production test cells of a size suitable for cars. So much further on than anyone else has been to this point.
