I've been hearing about these for a few years now. Huge if they work out at a large scale.

No one can figure out how to make them without costing a fortune.

    To be fair, solid state batteries went from being a pipe dream, to being only possible in perfect laboratory settings, to the current state of very real and possible -just expensive. And it has done all of this in about a decade. Just give it time.

    Mercedes will apparently be introducing SS batteries (not to be confused with the SS from Nazi Germany) in 2030. Not too far in the grand scheme of things. Then 2 or 3 years after that every car will have them unless China jumps the gun.
