Abstract: An additive that is added to the NaAlX4 electrolyte for use in a ZEBRA battery (or other similar battery). This additive has a moiety with a partial positive charge (δ+) that attracts the negative charge of the [AlX4]− moiety and weakens the ionic bond between the Na+ and [AlX4]− moieties, thereby freeing some Na+ ions to transport (move). By using a suitable NaAlX4 electrolyte additive, the battery may be operated at much lower temperatures than are typical of ZEBRA batteries (such as, for example, at temperatures between 150 and 200° C.). Additionally, the additive also lowers the viscosity of the electrolyte solution and improves sodium conductivity. Non-limiting examples of the additive SOCl2, SO2, dimethyl sulfoxide (DMSO, CH3SOCH3), CH3S(O)Cl, SO2Cl2. A further advantage of using this additive is that it allows the use of a NaSICON membrane in a ZEBRA-type battery at lower temperatures compared to a typical ZEBRA battery.
