Lithium is extremely abundant on earth. Unless we start launching it into space, or start building up after covering the surface with buildings and roads, we’re not going to run out. Lithium production capacity is scarce however, since it’s a mostly useless element unless you’re building batteries out of it. Anyway, once cities realize that they need to stop taking water from rivers, we should be able to skim quite a bit of lithium from desalination plant waste water.
