Document Type and Number:
Japanese Patent JP2001167759
Kind Code:
A
Abstract:
To provide a non-stoichiometric Zr-Ni-based hydrogen storage alloy for use in a negative electrode for Ni/MH secondary battery having a large capacity and a high performance.
Zr-based hydrogen storage alloy represented by the following general formula 1: Zr1-XTiX(MnUVVCrYNi1-U-V-Y)Z where X, U, V, Y and Z each independently represent an atomic fraction of the respective alloying elements or the like, and are values satisfying the following relationship: 0<X≤0.4; 0.3≤U≤0.4; 0.1≤V≤0.2; 0.0≤Y≤0.2; 0.45≤U+V+Y≤0.65; and 1.6≤Z≤1.9.
