A hydrogen storage alloy preferably used for electrodes in alkaline rechargeable battery is of the general formula: Zr1.2-aTiaMnvAlwNixMyCrz wherein M represents at least one element selected from the group consisting of Si, Zn, Sn, Fe, Mo, Cu and Co; and wherein 0.1 </= a < 1.2, 0.4 </= v </= 1.2, 0 < w </= 0.3, 0.8 </= x </= 1.6, 0 </= y </= 0.2, 0</= z </= 0.3, and 1.7 </= (v + w + x + y + z) </= 2.7. The alloy has at least one of a C14-type Laves phase of a crystal structure similar to that of MgZn2 and a C15-type Laves phase of a crystal structure similar to that of MgCu2 as a main alloy phase. <IMAGE> |
