Nickel metal hydride? NiMH has significantly lower specific energy than lithium, but reliability and cycle life are outstanding and well proven. I don't know if we're in any better shape on the nickel supply than we are on lithium and cobalt, or how nickel mining's environmental footprint compares with theirs. I see that nickel mainly comes from Indonesia, Philippines, Canada, and French New Caledonia. Those are relatively stable places. I think a lot of the reason that NiMH lost out to lithium for the current EV stable was the idiotic and immoral (should be criminal) patent emcumbrance. But that's expired, hasn't it? Yes? No?
