> To add to this, Tesla has had barely any battery progress on range and charge rate since 2018. A real concern is that no US battery manufacturer is working on manufacturing solid state batteries at scale. There are a few small US startups, but companies in China, Taiwan, Japan, and South Korea are spending many billions of dollars on this. Prologium now claims to have shipped 2.4 million units (cells, probably) from their first manufacturing facility. That's not a huge number of cells, but a year ago there were just lab samples. Mercedes is testing these and has some cars driving around with them. About 2x the energy density of lithium-ion batteries, reportedly. Safer, and 5 minute charging if you can find a powerful enough charger. Tesla isn't even rumored to be doing anything in this space. (While there's a lot of talk about Mercedes' 670 miles on a charge, what's probably going to sell are cars that have maybe 300 miles of range, are cheaper and weigh less. With 5 minute charging, there's less reason to lug a huge battery around.)
