摘要： A hydrogen-absorbing alloy electrode for metal hydride alkaline batteries uses as hydrogen-absorbing material a powder of a rare earth element-nickel hydrogen-absorbing alloy obtained by pulverizing thin strips of said alloy prepared by single roll process and having an average thickness of 0.08 to 0.35 mm and a minimum size of crystal grains present in the roll-surface size of at least 0.2 .mu.m and a maximum size of crystal grains in the open-surface side of not more than 20 .mu.m. A process for producing the above electrode is also provided. The electrode can provide, when used as negative electrode, metal hydride alkaline batteries which are excellent in both high-rate discharge characteristics at an initial period of charge-discharge cycles and charge-discharge cycle characteristics.

摘要： A first hydrogen-absorbing alloy electrode is obtained by applying a hydrogen-absorbing alloy powder on a collector or having a collector filled with a hydrogen-absorbing alloy powder and then sintering the hydrogen-absorbing alloy powder. The hydrogen-absorbing alloy powder is pre-pared by centrifugal spraying or gas atomizing and particles constituting the powder have a spherical shape, a nearly spherical shape, an egg-like shape or a mixed shape including the foregoing. The hydrogen-absorbing alloy electrode can readily be produced at low cost and have high packing density and good corrosion resistance, and can hence yield, when used for negative electrodes, metal hydride secondary batteries having excellent cycle characteristics. A second hydrogen-absorbing alloy electrode comprises a mixed powder containing a spherical-particle powder of a hydrogen-absorbing alloy and a powder as pulverized of the same alloy in a specific ratio. This electrode has high packing density and electronic conductivity, and can therefore gives batteries having excellent discharge characteristics on both high-rate discharge and low-rate discharge.
