Speaking of lithium batteries, I heard from some guy on the Business News that the world is oversupplied with lithium. There's enough to last for decades, apparently.

It's the second most common element in the universe.

Lithium isn't in the top 10 most abundant chemical elements in the universe ( https://en.wikipedia.org/wiki/Abundance_of_the_chemical_elem... ). The most abundant, of course, is hydrogen, making up close to 74% of all the baryonic mass, followed by helium ~24%. Lithium can be fused into heavier elements and the conversion happens efficiently in stellar environments where it is produced.

For every 10^6 atoms of silicon, there are only 10^3 atoms of lithium in the Earth's crust ( https://en.wikipedia.org/wiki/Abundance_of_elements_in_Earth... ).
