Hydrogen absorbing alloy for alkaline storage battery and method for preparing the same |
| abstract |
A hydrogen storage alloy, for use in alkaline storagenbatteries, having a CaCu 5 -type crystal structure andnrepresented by the compositional formula MmNi x Co y Mn z M 1-z n(wherein M represents at least one element selected from thengroup consisting of aluminum (Al) and copper (Cu); x is annickel (Ni) stoichiometry and satisfies 3.0 ≤ x ≤ 5.2; y isna cobalt (Co) stoichiometry and satisfies 0 ≤ y ≤ 1.2; z isna manganese (Mn) stoichiometry and satisfies 0.1 ≤ z ≤ 0.9;nand the sum of x, y and z satisfies 4.4 ≤ x+y+z ≤ 5.4). Thenhydrogen storage alloy includes a bulk region having anCaCu 5 -type crystal structure and a substantially uniformncomposition and a surface region surrounding said bulknregion and having a graded composition. When the sum innpercentage of numbers of cobalt (Co) atoms and copper (Cu)natoms present in the surface region is given by a and thatnin the bulk region by b, the relationship a/b ≥ 1.3 isnsatisfied. |
