THE INFLUENCE OF CALCIUM COMPOUNDS ON THE BEHAVIOR OF THE NICKEL ELECTRODE

The nickel hydroxide electrode normally exhibits a poor change-accepta nce which results from the competitive reactions of the oxidation of a ctive material and the evolution of oxygen. The combined addition of c obalt and a calcium compound to the nickel hydroxide can improve appre ciably the utilization and discharge potential of the active material. The action of the calcium additive is to increase the oxygen evolutio n potential, while the cobalt imparts good conductivity to the active material for both electrons and protons.
