Abstract
A method for manufacturing a hydrogen-occlusion-alloy electrode is provided, wherein a hydrogen-occlusion-alloy ingot is mechanically crushed, the obtained powder is washed in water to remove dust-size particles from the surface thereof, the washed powder is used in a moisten state after said washing as it is to prepare a slurry of a specified composition, and the slurry is supported on to a current collector. Incorporating this hydrogen-occlusion-alloy electrode in a nickel-hydrogen storage battery as the negative electrode leads to reduced internal pressure of the battery, an extended charge and discharge cycle life, and an improved rapid discharge characteristic.
