There's not enough lithium on planet Earth even for all the electric cars we'll need, don't even start on using lithium batteries for large-scale storage.

The only hope here is that Magnesium-based batteries will become a thing.

EDIT: OK, it seems that I mistook the "mineable lithium deposits" number for the whole lithium available :)

Anyway, unless there is a major technological breakthrough we are looking at few decades of lithium shortages. I expect countries to actually fight wars over lithium they way the US used to fight over oil. So, in the end, building nuclear plants seems more reasonable than building solar and then praying for cheaper batteries.
