Abstract
This invention relates to a hydrogen storage active material comprising an alloy having the formula MmNi.sub.5-x-y-z Zn.sub.x Q.sub.y R.sub.z, in which Q.dbd.Al, Ca and Sr, R.dbd.Li, Na and K, 0<x.ltoreq.1, 0<y.ltoreq.0.8 and 0<z.ltoreq.1. An alloy phase of zinc is formed between the surface coating and the alloy base after treatment of the alloy powder by surface plating. As a result, the electrochemical capacity as well as the life of the hydrogen storage alloy electrode formed is increased significantly while the cost is greatly reduced by employing Zn.
