Abstract
The structure of porous electrodes made from pressed dendritic zinc has been varied to improve the efficiencies of zinc utilization during low temperature discharges. The effects of varying the composition of the plating bath and the rate of deposition of dendritic zinc were investigated as was the use of different binders and current collectors. When samples of the optimized electrode were discharged in zinc/air bicells at a current density of 16 mA/square cm, zinc utilization of from 23% at -40C to 91% at 50C were recorded.
