PURPOSE:To improve the sintering property by mixing a power consisting of one or more of cobalt, nickel, and TiNix as a sintering auxiliary with a hydrogen storage alloy power, and then pressure molding the mixture to reduce the porosity. CONSTITUTION:A power consisting of one or more of Co, Ni and TiNix is mixed with a hydrogen occluding alloy powder. This mixed powder is subjected to pressure molding with disposing a metallic porous plate in the center, and the resulting compact is sintered in vacuum or in an inert atmosphere to obtain an electrode. Hence, as the strength as a sintered body is high, a sufficient strength as the electrode can be obtained, the discharge characteristic is improved, and thus a battery having satisfactory properties can be obtained also without loosing the charge characteristic. |
