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.
Comment on New sodium ion battery stores twice the energy and desalinates seawater
Honytawk@discuss.tchncs.de 21 hours agoIf 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.
