PURPOSE:To provide a sealed nickel-hydrogen battery having enhanced effectiveness against an internal pressure rise for ensuring an advantage in sealing a nickel-hydrogen battery. CONSTITUTION:A cobalt compound, for example, cobalt monoxide 11 is added to and mixed with one or more of battery components of a negative electrode, a positive electrode, an electrolyte and a separator. Thereafter, bivalent complex cobalt ions generated in the electrolyte are reduced, thereby forming a cobalt layer 12 on the surface of hydrogen storage alloy powder. This battery is characteristic in that the negative electrode so made is used. |
