Tesla never really figured out batteries. The cell building sections of Tesla's battery plant are run by Panasonic or LG. Tesla's own people just package them up into a big battery box.
As far is known publicly, Tesla has no solid state battery program. Everybody else who's big in batteries in Asia has a major solid state battery program. Volume production is still hard, but one vendor has made over 2 million samples, some of which are in test vehicles.
The expected performance of solid-state batteries is 500Wh/kg, 5 minute charge, survive nail test without fire or explosion. China is mandating that safety requirement after July 2026.[1]
The beginning of the end of classic lithium-ion is in sight.
