> The EV sector uses a combination of lithium-ion battery chemistries, with cobalt-containing cathodes maintaining the largest share. This is due to their energy density and performance –cobalt is particularly important for stability and safety.

I will mention that i mistyped in my previous comment, i meant to say long range EV’s. I believe a number of manufacturers are moving to cobalt free batteries for their standard range models, but most of the long range models require the higher capacity cobalt batteries at this point.
