More Information
Summary:A hydrogen storage alloy suitable for a negative electrode of an alkaline storage battery is provided. The hydrogen storage alloy provided is a hydrogen storage alloy used for an alkaline storage battery that has, as a main phase, one or two crystal structures selected from an A2B7-type structure and an AB3-type structure, and that is represented by a general formula: (La1-a-bCeaSmb)1-cMgcNidAleCrf (where suffixes a, b, c, d, e, and f in this formula (1) meet the following conditions: 0<a≤0.15; 0≤b≤0.15; 0.17≤c≤0.32; 0.02≤e≤0.10; 0≤f≤0.05; and 2.95≤d+e+f≤3.50.
