Abstract
A battery including a polar solvent transportive, ionically conductive separator formed directly on an electrode is prepared by applying a coating composition containing a polymer or gel dispersed in a polar solvent directly to the electrode surface and solidifying materials in the coating composition to form a separator membrane.
Claims2
A battery comprising first and second electrodes, an alkaline electrolyte, and an ionically conductive separator disposed between the electrodes, the separator being formed by applying a coating composition to the surface of at least one of the electrodes and solidifying material contained in the coating composition, the coating composition comprising a gel or polymer dispersed in a polar solvent, wherein the separator occupies less than 10 percent of the volume of the battery and said separator has a solvent content greater than 90% by weight.
