The Silver Oxide-Zinc Alkaline Primary Cell. Part 2. Effects of Various Types of Negative Electrodes on Cell Characteristics
Abstract
The silver oxide-zinc alkaline primary cell consists of a negative electrode of zinc, a positive electrode of silver peroxide, and an alkaline electrolyte (generally a potassium hydroxide solution). During discharge, the silver peroxide in the positive electrode is reduced to metallic silver and the metallic zinc in the negative electrode is oxidized either to zinc oxide or to a complex zincate ion. The reactions involved have not been fully determined and may prove to be fairly complex. Because of its many desirable characteristics, an appreciable demand has arisen for this cell. It is a constant voltage, primary cell of low weight and volume, capable of operating at high current densities over a wide range of temperatures. Wherever the demand for the cell is based on minimization of weight or volume, a separate design generally will be needed for each set of conditions. Such a design will require more detailed information than is necessary for the construction of ordinary types of batteries.
