Abstract
The performance of porous, silver‐silver oxide electrodes decreases rapidly below 0°C, and galvanostatic discharge curves show several different regions. Most of the work reported here was done on thin electrodes, prepared by electrodeposition or by powder pressing. An attempt is made to explain the regions in the discharge curves, and the apparent Tafel parameters, from a plausible kinetic mechanism. The application of theories of porous electrode behavior is demonstrated by results from thick electrodes made by stacking thin electrodes together. The use of the information in designing electrodes is discussed, as is future work.
