I thought sodium batteries had considerably less energy density than conventional? Is that not a problem anymore?

They indeed have less energy density, but I don’t get your point about less safety. They work better in high and low temperatures, can be charged a lot faster and don’t degrade as fast. Sodium isn’t as reactive as Lithium, lowering the risk of fires.

My point is that if they have less energy density, they aren’t a particularity great choice for EVs, as the increased battery size to get the same capacity makes the whole thing much heavier, requiring even more battery to move it. I guess for like short range vehicles, it might be fine, but at least around here, thats gunna be a pretty tough sell, because everything is spread out. It can’t really make EVs safer if its not being used for them due to the drawbacks, is all.
