Abstract

See full text

A hydrogen storage alloy preferably used for electrodes in an alkaline storage battery is provided. The alloy is of the general formula ZrMn.sub.w V.sub.x M.sub.y Ni.sub.z which comprises C15-type Laves phases having a crystal structure similar to that of MgCu.sub.2 as a main alloy phase, where M is an element selected from the group consisting of Fe and Co; w, x, y, and z are respectively the mole ratios of Mn, V, M and Ni to Zr; the conditions 0.4.ltoreq.w.ltoreq.0.8, 0.1.ltoreq.x.ltoreq.0.3, 0.ltoreq.y.ltoreq.0.2, 1.0.ltoreq.z.ltoreq.1.5 and 2.0.ltoreq.w+x+y+z.ltoreq.2.4 are satisfied.
