Coming back to the matter at hand, there's a lot of new battery technologies and I strongly believe that current evs will be able to switch from Lithium if a better technology comes. Also Lithium batteries are recyclable so they might become useful to store energy in the grid, though I barely see investment for it worldwide.
Nuclear for me seems more and more as a silver bullet, together with the various renewables and grid storage. But this is just energy production, we still have a lot of things to stop burning fuels that right now seem damn impossible.
