Abstract

PURPOSE: To increase the oxidation-resistant property of a negative electrode and to improve the stabity of the cell internal pressure and the cycle life by mixing a metallic condition of nickel layer and cobalt layer, and an oxide layer of at least one component of the alloy components to the surface of the alloy powder of a hydrogen storage alloy negative electrode.
CONSTITUTION: To the surface of a hydrogen storage alloy, not the alloy condition of nickel and cobalt, but a metallic condition of nickel layer and cobalt layer, and an oxide layer of La, Ce, Co, Mn, or the like which is at least one component of the alloy components are mixed, and a hydrogen storage alloy negative electrode including these powders and a binder, and a nickel oxide positive electrode are contacted closely through a separator to form an electrode body, which is housed in a battery container, and an electrolyte is poured and sealed. As a result, at the oxidation-resistant property in the electrolyte, and in an overcharged condition, the resistance to oxidation to the oxygen gas generated from the positive electrode is increased, and the service life of the battery is improved.
