SILVER-ZINC ELECTRODES AND SEPARATOR RESEARCH

Abstract

Additions of 1.2% to 2% lignosulfonic acid in the negative mix is helpful to negative plate cycle life. The use of cotton fibers helps to maintain the negative plate active material in place during cycle life. The surfactant BC-610 is the best choice for use in the zinc negative material found to date. However, at cold temperatures, surfactants appear to inhibit cycle life. The use of .1% Ethanol in the negative material helps cell cycle life as well as surfactant FC-95. Small percentages of acicular ZnO mixed with Kadox-15 appear to help negative plate cycle life. The use of 2% to 5% ZnSO4 aids the negative plate cycle life at room temperature but is detrimental to cold (30-40 F) operation. The best electrolyte to date at 60% depth-of-discharge is 50% KOH yielding 220 cycles.
