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： An additive that is added to the NaAlX 4 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 [AlX 4 ] - moiety and weakens the ionic bond between the Na + and [AlX 4 ] - moieties, thereby freeing some Na + ions to transport (move). By using a suitable NaAlX 4 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 SOCl 2 , SO 2 , dimethyl sulfoxide (DMSO, CH 3 SOCH 3 ), CH 3 S(O)Cl, SO 2 Cl 2 . 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.
摘要翻译：添加到用于ZEBRA电池（或其他类似电池）中的NaAlX 4电解质的添加剂。该添加剂具有部分正电荷（δ+），其吸引[AlX 4] - 部分的负电荷并削弱Na +和[AlX 4]部分之间的离子键，从而释放一些Na +离子输送（移动）。通过使用合适的NaAlX4电解质添加剂，电池可以在比典型的ZEBRA电池（例如在150至200℃的温度下）低得多的温度下操作。此外，添加剂还降低了电解质溶液的粘度并提高了钠电导率。添加剂SOCl2，SO2，二甲基亚砜（DMSO，CH3SOCH3），CH3S（O）Cl，SO2Cl2的非限制性实例。使用这种添加剂的另一个优点是，与典型的ZEBRA电池相比，它允许在较低温度下在ZEBRA型电池中使用NaSICON膜。
