I believe it melts when it gets hot. Not sure if you need to keep it hot enough to stay molten... By the way, this is not new tech! What excited me here is the prospect of bringing these batteries into large scale production. Imo, this is the kind of thing that could transform how we heat and cool homes and other buildings.
