Lithium: 33
Lead: 37
Antimony: 62
- timdiggerm 12y agoWell they are more common
- mtdewcmu 12y agoThat table uses a mass-based unit, so wouldn't that tend to create the misleading impression that lighter elements are more scarce? Energy storage capacity depends on the number of atoms, not mass (as you can intuit by comparing lithium batteries to lead or nickel-cadmium batteries -- heavier doesn't mean more powerful).
- p1mrx 12y agoWell, if Pb and Sb are more scarce than Li by mass, then they're even more scarce when you're counting atoms. If Ambri's technology does pan out, it will be due to a cheaper manufacturing process, not because they're avoiding lithium.
- mtdewcmu 12y agoI thought those numbers were showing that lead and antimony are more common than lithium.
