Title: Nickel electrode for alkaline storage battery
Inventor: INOUE MASAO
IPC: H01M4/52
Filed: 1996-12-11
Abstract: PROBLEM TO BE SOLVED: To enhance conductivity of nickel hydroxide, deepen discharge depth, and enhance the utilization factor of an active material by adding at least one of a manganese compound, bismuth compound, and aluminum compound to a nickel hydroxide in which the surfaces of particles are covered with a cobalt compound having a mean valence of cobalt of larger than 2, and using the obtained material as the active material.

If the oxidation number is too much high, the conductivity of the cobalt compound is decreased, and the utilization factor of the active material is decreased. The mean valence of cobalt in the cobalt compound for covering the particle surfaces of the nickel hydroxide is preferable to be 2.5-2.93.
