PURPOSE:To provide a nickel electrode excellent in charging efficiency at the time of high temperature by preventing oxygen generation which is decomposition reaction of an electrolyte at charging time. CONSTITUTION:In a plate using nickel hydroxide serving as an active material, a metal element of zinc, cadmium, cobalt, lead, copper, ruthenium, indium or tungsten in a corrosion region by an alkaline water solution is contained in a particle fine hole of this nickel hydroxide. In this way, oxygen generating potential is shifted to negative, to obtain high oxygen overvoltage. |
