SELF-DECOMPOSITION PROCESSES IN SILVER ELECTRODES.

Article abstract of DOI:10.1149/1.2096173

The self-decomposition of silver oxide (AgO) electrode material in KOH electrolyte has been studied to determine the effects of metallic additions, preparation techniques, and carbonate content. The study employed a multi-technique approach that involved direct gas evolution measurements, thermal analysis, and electrical resistivity measurements. The results indicate that small amounts (10 ppm) of cobalt and nickel substantially increase the rate of decomposition in electrolyte. High levels of copper also increase the decomposition rate, but to a lesser extent. Other metals, such as indium and gold, tend to suppress AgO decomposition. A third group, including lead and mercury, have little or no effect on the decomposition rate. Binary mixtures of several elements were also tested as a means of counteracting the destabilizing properties of cobalt in particular.
