None of those are either rare earth metals or especially rare, graphite isn't a metal at all, and lithium iron phosphate batteries contain neither nickel nor manganese.

This should say, "neither cobalt nor manganese". They do contain nickel.
I don't think there's any nickel, and Wikipedia agrees, but I always love a correction:
"LFP contains neither nickel[35] nor cobalt, both of which are supply-constrained and expensive. "

I'm an idiot, you're right.
