Abstract : This invention provides a secondary battery containing a chloroaluminate molten salt electrolyte and a positive component capable of sodium or lithium intercalation. The preferred battery configuration incorporates a molten sodium negative separated from the chloroaluminate salt electrolyte by a solid separator such as a sodium - beta - alumina ceramic which possesses a high ionic conductivity for Na+ ions. Either a NaA1C14 fusible salt is preferred as the electrolyte component. The latter electrolyte is unique in intercalation batteries in general, since both Na+ and Li+ intercalation can occur simultaneously. The former electrolyte is limited to Na+ intercalation during the discharge reaction. TiS2 is a favored positive solid solution electrode, although there are other possible transition metal oxides, sulfides, and selenides which could serve the function.
