摘要： The present invention provides a secondary cell having a negative electrode compartment (15) and a positive electrode compartment (25), which are separated by an alkali ion conductive electrolyte membrane (40). An alkali metal negative electrode (20) disposed in the negative electrode compartment (15) oxidizes to release alkali ions as the cell discharges and reduces the alkali ions to alkali metal during recharge. The positive electrode compartment (25) includes a positive electrode (30) contacting a positive electrode solution (35) that includes an alkali metal compound and a metal halide. The alkali metal compound can be selected from an alkali halide and an alkali pseudo-halide. During discharge, the metal ion reduces to form metal plating on the positive electrode. As the cell charges, the metal plating oxidizes to strip the metal plating to form metal halide or pseudo halide or corresponding metal complex.

摘要： The present invention provides a molten sodium secondary cell (10). In some cases, the secondary cell (10) includes a sodium metal negative electrode (20), a positive electrode compartment (25) that includes a positive electrode (30) disposed in a liquid positive electrode solution (35), and a sodium ion conductive electrolyte membrane (40) that separates the negative electrode (20) from the positive electrode solution (35). In such cases, the electrolyte membrane (40) can comprise any suitable material, including, without limitation, a NaSICON-type membrane. Furthermore, in such cases, the liquid positive electrode solution (35) can comprise any suitable positive electrode solution, including, but not limited to, an aqueous sodium hydroxide solution. Generally, when the cell (10) functions, the sodium negative electrode (20) is molten and in contact with the electrolyte membrane (40). Additionally, the cell (10) is functional at an operating temperature between about 100°C and about 170°C. Indeed, in some instances, the molten sodium secondary cell (10) is functional between about 110°C and about 130°C.

摘要： 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.
