Effect of the Electrolyte Concentration on the Reversibility of a Nickel Oxide Electrode in a Nickel-Zinc Battery

摘要

The degree of charging of a nickel oxide electrode composed of spherical nickel hydroxide in a nickel-zinc battery was studied in anodic oxidation of the electrode in KOH solutions of different concentrations,containing hydroxozincate ions.The use of a nickel oxide electrode composed of spherical nickel hydroxide on a foamed nickel support (FNi NOE),instead of a metal-ceramic (MC) electrode,in nickel-cadmium (NiCd) and nickel-metal hydride (NiMH) batteries made it possible to markedly simplify the production process and raise by 30-50% their electrochemical parameters.
