Nickel Hydroxide Electrode Research
Abstract
The report discusses results of work performed to develop an improved nickel hydroxide electrode for use in rechargable alkaline electrodes for aerospace applications. Voltametric cycling studies have shown that all deliberate additions of cations (cobalt, zinc, cadmium, aluminum, and lithium) to the active material have a beneficial effect on the performance of the Ni(OH) 2 electrode. None of these additives showed any negative effects. Cobalt and zinc were the most effective with regard to high active mass utilization, capacity maintenance with cycling, and charge efficiency, especially at higher temperatures (45C). The fact that the thickness of all heavily loaded sintered plates increased by about 20% during cycling suggests that the active material has a much lower density in the charged state and that the above value may therefore be near the maximum attainable energy density with sintered structures under sealed-cell conditions.
