Sodium ion batteries have less energy density as opposed to Lithium ion (100-150 WH per Kg instead of 150-250). I'm curious how much these "wet" batteries improve that. The article doesn't say.
Nonetheless, even if it's not the new battery for your car, it could be useful as energy storage for the grid, storing green (solar) energy for the night, and desalinating seawater at the same time.
We hear about a new battery chemistry like every week. Do most never get to commercialization?
No, that's why we use the same batteries Voltaire did on his frogs.
Voltaire was a French poet.
Alessandro Volta was the electrochemist.
JFC..what do they teach in schools any more?
Well, I know the difference between alkaline, NiCd, NiMH, and lithium batteries, and that they don't grow on trees, so at least I have that.
