@@maheshvarah monopoly of battery then, better we hack current engineer with some help from latest battery tech, electrolysis + sodium ion battery will become 100% green fair market, than 100% battery which only some have access to that resource.
Ferrocyanide = prussian blue. But it is a battery grade prussian blue. One is made with iron sulfate for paint. Battery grade is made with ferrochloride. No sulphur.
There isn't that much of a difference compared eg with LFP & if you go to the pack level, the lower requirements for cooling mean a simpler construction that pulls Sodium based packs closer to lithium ones. . Add a much lower price for supporting materials (electrodes from carbon & aluminum contact's instead of copper) & the natrium battery becomes a viable competitor.
Energy storage for homes, industries and grids don’t require so much energy density, but high cyclelife and security and cheaper costs. This Na -ion batteries will provide all of this things.
