And lithium isn't exactly rare. There may be rare earth materials required in small amounts for high-efficiency electric motors but lithium is plentiful. Current proven high-quality ore deposits are sufficient to at least 2100 (assuming 1 billion EVs are built between now and then).

Plus lithium recycling technology is advancing quite fast as well.
