RE:This company isn't going to make it.... I am not an expert but solid state battery still have a cathode and an anode if not well there is no charging/loading cycle so no electricity at all. The difference is there is no electrolytes between them which means it is safer and cheaper.
secondly Hydroquebec is making the solid state battery since 1980 and Toyota are using their technology as Tesla is currently doing with the lithium ion battery.
pretty sure they will be using graphite with silicone as well and same for graphene battery... good try to bring down the stock !
