I believe that would be lithium.

You should read up on what rare earth metals are. Lithium isn't one of them. They're on the opposite side of the product table. It's not even "rare" in the conventional sense. It ranks between lead and cobalt in abundance in the Earth's crust. Finally, it takes up only about 2.5% of the weight of a typical EV battery. Yes, we're currently in short supply during the rapid run-up in the EV market but it's also nearly perfectly recyclable, meaning eventually exhausted EV batteries will become a major source of lithium in new ones. That is, unless we move to another battery chemistry by then!

Coolio. Thanks for reading up so I don't have to! What is the answer to the original question then?
