Degradation of organic battery separators through reaction with the active mass of silver oxide electrodes led to an investigation of inorganic separators. It was shown in studies with inorganic separators deposited electrophoretically directly on to electrodes that separators made of calcium sulfate, calcium hydroxide, magnesium oxide, and zirconium oxide possess high chemical stability in the alkaline electrolyte, are practically inert with respect to the electrochemical properties of the silver and cadmium electrodes, and have a highly developed structure that serves to inhibit the diffusion of silver ions and organic molecules. The small additional resistance created by the inorganic separator has an effect on the discharge voltage only at low temperature and high current density. It was found that the shelf life of charged silver--cadmium power sources with the inorganic separators studied is 1.5 to 2 times as long as that of power sources without such separators. The long charge retention was attributed to lower reduction rates of the silver oxides. Separators of zirconium oxide have optimum properties for use in silver--cadmium batteries. 2 figures, 1 table.
