Abstract: A divalent silver oxide cell of the type having a positive electrode formed mainly of divalent silver oxide has its stability greatly improved by adding a cadmium component and a tellurium component and, optionally, at least one auxiliary component containing an element selected from the group consisting of thallium, mercury, lead, germanium, yttrium, tin, tungsten, lanthanum, rare earth elements, zinc, aluminum and selenium, each to either the divalent silver oxide, the alkaline electrolyte, or both. The cadmium component is contained in a concentration of not less than 0.03% by weight when in the divalent silver oxide and not less than 0.01 g/liter when in the alkaline electrolyte; and tellurium component in a concentration of not less than 0.01% by weight when in the divalent silver oxide and not less than 0.01 g/liter when in the alkaline electrolyte; and the at least one auxiliary component in a total concentration of not less than 0.01% by weight when in the divalent silver oxide and not less than 0.
