ALKALI METAL ION BATTERY USING ALKALI METAL CONDUCTIVE CERAMIC SEPARATOR

摘要

A battery (100) having a first electrode (104) and a second electrode (108). The first electrode (104) is made of metal and the second electrode (108) is made of an oxidized material that is capable of being electrochemically reduced by the metal of the first electrode (104). An alkali-ion conductive, substantially non-porous separator (120) is disposed between the first (104) and second electrode (108). A first electrolyte (134) contacts the first electrode (104). The first electrolyte (134) includes a solvent (154) which is non-reactive with the metal, and a salt bearing an alkali ion that may be conducted through the separator (120), wherein the salt is at least partially soluble in the solvent (120). A second electrolyte (138) is also used. The second electrolyte (138) contacts the second electrode (108). The second electrolyte (138) at least partially dissolves the salt that forms upon the oxidized material being electrochemically reduced.
