> And assume we increase battery supply by 40x (even though lithium price is going up dramatically now). It sounds like you're assuming at large scale, Lithium is required for storage (it's not - consider pumped water), and at small scale Lithium is required for storage (it's not - consider flow batteries). Point being, increasing storage by 40x is not infeasible because of any constraints around Lithium cost / availability.
