Can we just skip to solid state batteries please?
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.
BYD is rumouredo introduce them next year. They filed multiple patents this year and the rumours have been ongoing for years that 2027 is the target year.
You had me at "not to be confused with..." but I'm pretty sure they made the batteries for them too.
