Abstract : Tests utilizing a catalyst indicate that the recombination of gases appears to be chiefly dependent on the quantity of catalyst present. It is apparent that internal cell pressure affects cycle life, i.e., high internal pressure reduces cycle life somewhat and low internal pressure increases life. Certain zinc crystal sizes may be detrimental to cycle life. Additional studies are to be made. The additions of various impurities to the cell, such as FeO, MnO, and K(2)CO(3), do not appear to be detrimental to cycle life of the silver-zinc cell. The use of the surfactant Emulphogene (about 1%) apparently aids in the cycle life of the zinc negative plate. Higher percentages are to be tested. A new plastic styrene-based resin is to be tested in cell cases and covers. (Author)
