发明名称 LOW TEMPERATURE SECONDARY CELL WITH SODIUM INTERCALATION ELECTRODE
摘要 The present invention provides a molten sodium secondary cell. In some cases, the secondary cell includes a sodium metal negative electrode, a positive electrode compartment that includes a positive electrode disposed in a molten positive electrolyte comprising Na-FSA (sodium-bis(fluorosulonyl)amide), and a sodium ion conductive electrolyte membrane that separates the negative electrode from the positive electrolyte. One disclosed example of electrolyte membrane material includes, without limitation, a NaSICON-type membrane. The positive electrode includes a sodium intercalation electrode. Non-limiting examples of the sodium intercalation electrode include NaxMnO2, NaxCrO2, NaxNiO, and NaxFey(PO4)z. The cell is functional at an operating temperature between about 100 C and about 150 C, and preferably between about 110 C and about 130 C.
