The problem is there are multiple tech companies involved, all bullshitting each other. It starts with a German screening technology company claiming they can screen produce the solid state electrode, when they never made a single battery ever. if company A can develop the tech then company B can assemble the battery to do into the motorcycles in company C.

Formula E racing uses the state of the art in batteries, and for 2027 they sourced a lithium battery even though cost was no object.

Two Chinese companies claim to be making solid state batteries, put the performance is only equal to classic lithium.

Toyota got burned on this. They were promised SS batteries delivered by 2025. Never happened.
