- fooker 3y agoThere is an additional step here - electrolysis to separate sodium and chlorine. The energy cost of that is not a solved problem.
- Tagbert 3y agoTrue but the mass of lithium or sodium in a battery is limited. A Tesla Model S which has a large battery uses 62.6 kg (about 130 pounds) of lithium. You only need to separate that once. This limits the amount of energy needed to produce that battery. That is unlike the ongoing energy needed to refine the gasoline in an ICEV.
