摘要：The invention provides a hydrogen absorbing alloy electrode obtained by thestep Pof preparing a hydrogen absorbing alloy powder containing cobalt and nickel, thestep Pof subjecting the surfaces of the alloy particles to a reduction treatment with high-temperature hydrogen by holding the powder in a high-temperature hydrogen

atmosphere under the conditions of temperature, pressure and time sufficient to reduceoxides formed in a surface layer portion of each of the alloy particles, not melting thealloy particles and not permitting the alloy particles to absorb hydrogen, the step Poftreating the resulting powder with an acid or alkali by immersing the powder in an acid oralkaline aqueous solution, followed by suction filtration, washing with water and drying,and the step Pof applying the resulting power to an electrically conductive substrate andshaping the substrate in the form of the electrode. The electrode thus provided hashigher activity than conventionally.
