Na-Ion can be a lot less expensive. But it's a lot heavier. (Not a problem for grid-storage.)

Have they eliminated the need for sodium to be molten in sodium batteries? If so, that's great news!

IIRC sodium is the -cathode- in the battery. No molten (RU thinking of reactors?)

I'm not thinking of reactors, though I am aware that molten sodium is used as a coolant fluid. It seems that I was remembering an off-hand comment in a MinutePhysics video from a few years ago. Molten sodium batteries do exist, but regular sodium batteries also exist.
