Grid-scale storage (and increasingly EVs) use lithium-iron-phosphate battery cells, which don't require cobalt/nickel/manganese.
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. "
