I used to think this too, until solar started to take off unexpectedly. We will need nuclear in the long run, but at the moment, I don't think massive adoption is a necessity.
As for Lithium, even if Li-ion remains the best technology we have for the next ten years (which it might not be? [1]), we should be able to find better ways of mining Lithium [2], like electrolysis from seawater. After all, it's probably the most abundant metal in the universe.
