Abstract : AINED FOR 50 CYCLES FROM A ZINC-AIR CELL BY: (a) containing the zinc anode within a plastic frame onto which the separator layers were epoxy-sealed, (b) blocking the edges of the anode with a thin plastic shield, and (c) providing a 20 to 30 mil thick electrolyte channel between the charging electrodes and separator clad anode. Preliminary results from sealed zinc-oxygen cell investigations indicate that good capacity maintenance can be attained by: (a) sealing the charging electrode within a plastic frame onto which a layer of potassium titanate paper is epoxy-sealed to the edge of the electrolyte face and a thin porous teflon layer is cemented to the gas face, (b) using silver-amalgam catalyzed oxygen electrodes, and (c) adding 5% potassium titanate powder to the zinc oxide mix.
