There's more than 4 though. Lithium of course, then Cobalt/Manganese/Nickel for the cathode, Graphite & Copper for the anode, High Purity Alumina for separators. And then of course there's the potential for Zinc + Nickel (or Silver) batteries to be developed enough such that they form a viable, maybe preferable, alternative to lithium-ion - and Zn is already in a strong bull market with supply tightening, so that's another mineral to add to the list.
