Comment on New sodium ion battery stores twice the energy and desalinates seawater

Sodium-ion batteries are not hype though, they are in production use in multiple industries already. They are generally superior to Lithium based batteries in all regards, with the exception of having a bit lower energy density. An equivalent LiFePO4 battery might be 70-80% of the size for the same storage. It’s not a big deal for large applications like cars and solar storage.

Yeah, the advantages of all these sodium batteries, in my mind, is that they are stable and rugged enough to build up a backbone of a energy storage system for a grid. I’m seriously thinking about them for my house, in the UK.

  Also not nearly as much of a fire hazard.

  Yes, I am very intrigued. For something size of half a shipping container I could power my house for almost a month. This is of course fantasy because I don’t have $20,000 to throw down. But combine it with solar cells that have gotten really cheap you could indefinitely power you house for next to nothing.

If they have a bit lower energy density than Lithium batteries, then where does the claim that they store twice the energy come from?

  Twice the energy than the previous sodium battery tech. Nowhere does it say its twice as good as Li-ion. That’s an assumption you made.

  Sounds like it came from that article about the new kind of sodium batteries with vanadium that are doing that desalination business. I was describing the general technology rather than that specific new one in the article.
