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 an electrochemical cell having an negative electrode compartment and a positive electrode compartment. A solid alkali ion conductive electrolyte membrane is positioned between the negative electrode compartment and the positive electrode compartment. A catholyte solution in the positive electrode compartment includes a halide ion or pseudohalide ion concentration greater than 3M, which provides degradation protection to the alkali ion conductive electrolyte membrane. The halide ion or pseudohalide ion is selected from chloride, bromide, iodide, azide, thiocyanate, and cyanide. In some embodiments, the electrochemical cell is a molten sodium rechargeable cell which functions at an operating temperature between about 100° C. and about 150° C.

摘要： An electrochemical cell (100) in accordance with one embodiment of the invention includes a first electrode (102a) containing a first phase intermixed with a second phase and a network of interconnected pores. The first phase contains a ceramic material and the second phase contains an electrically conductive material providing an electrically contiguous path through the first electrode (102a). The electrochemical cell (100) further includes a second electrode (102b) containing an alkali metal. A substantially non-porous alkali-metal-ion-selective ceramic membrane (104), such as a dense Nasicon, Lisicon, Li β"-alumina, or Na β"-alumina membrane, is interposed between the first (102a) and second (102b) electrodes.
