    Maybe you should look into the operating principles before you declare them ‘infeasible’. They’re a vessel filled with antimony, magnesium and a liquid salt electrolyte that self-separates according to specific gravity. Since both the anode and cathode are made of liquid metal, there’s no structural degradation over time. They can be trivially scaled to just about any size you like and are made exclusively from Earth-abundant cheap elements. Just about the only tricky thing is that the operating temperature of a working cell is 600C, but that’s hardly an issue for a grid-level storage facility.
