Na-Ion can be a lot less expensive. But it’s a lot heavier. (Not a problem for grid-storage.)
Can we eat them?
BYD is supposedly bringing them to production.

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?
Good point !
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!
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.

Most likely because the news is in English. And why would Natrium be better on an international forum?
It is Sodium in most Latin languages (despite Natrium being Latin), in Hindi and in Arabic. And Chinese has a different root. Among the 10 most spoken languages (according to Wikipedia), only Russian is using Natrium.

I’m a PhD candidate in chemistry. I’ve never once seen sodium refer to the salt, sodium chloride. Sodium is the metallic form or the atom.
However, why sodium, tungsten, lead, antimony, tin, silver, gold, mercury, iron, and potassium and not their Latin forms? Natrium, wolfram, plumbum, stibium, stannum, argentum, aurum, hydrargyrum, Ferrum and kalium? I don’t really know. Mostly it’s just fun trivia for me to tell the undergrads.
I always said salt, of sodium chloride for NaCl. Who is using sodium for table salt? The only time I heard that associated was when saying that table salt is a source of sodium, which is true.
