- Robotbeat 9y agoSodium is not fundamentally better material than lithium, though. It's just a bit more abundant (but lithium is very abundant and can be extracted from actual ocean water, though because of lithium's abundance, that will never be the cheapest way to get lithium). Lithium is the third lightest element and the lightest (regular) metal. Sodium is much heavier.
