Toyota and other companies are going to a sold state battery thta is half in size and uses no or very little lithium and is right now 30% less cost to produce. SSB are also way less expensive and are very fast charging.

I guess you didn't read (or comprehend) the article that you posted. It says the very opposite of what you said.

WHY IS IT DIFFICULT TO MASS PRODUCE SOLID STATE BATTERIES?
Carmakers and technology companies have produced solid-state li-ion battery cells one at a time in a lab, but have been unable so far to scale that up to a mass production.
It is hard to design a solid electrolyte that is stable, chemically inert and still a good conductor of ions between the electrodes. They are expensive to fabricate and are prone to cracking because of the brittleness of the electrolytes when they expand and contract during use.
Currently, a solid-state cell costs about eight times more to make than a liquid li-ion battery, experts say.

OK I jumped the gun. Reading too many articles.

BY 2025 Ford etc predict SSB will match Lithiums price.
The deal is though SSB achieve faster charging, they are smaller and thye do not catch fire.
