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

As a flashlight enthusiast, I'd be very interested to see if sodium batteries are any better.

Battery-licking good!

At least once, yes

They are already in production, and sold to consumer, since few days. A french start up is selling an electric screwdriver with a sodium battery.

So the answer to the question about what to do with the excess salt from desalination plants, is make batteries?

Now we just need a lot of swimming pools for the chloride.

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

[–] kalkulat@lemmy.world 2 points 1 year ago (1 children)

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.
