Thank you. Among other important points there:

"That said, Japan isn't the only country pursuing lithium recovery. In the US, Redwood Materials – the recycling company founded by former Tesla CTO JB Straubel – says it's already recovering 95% of lithium from the equivalent of about 250,000 EVs per year."

EV batteries are too large and valuable to wind up in landfills, although I'm sure it has happened somewhere. I do like that Japan is is making it harder to just throw out smaller lithium batteries. That strikes me as a more probable source of waste.
