Document Type and Number:

Japanese Patent JP3903114

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To extend the life cycle of a nickel-metal halide-alkaline battery at a high temperature.
SOLUTION: An alloy used for negative electrode activator of a rechargeable nickel-metal halide-alkaline battery comprises a composition given by Mm1-uEuNivCowAlxMnyMzo. In the above formula Mm designates a lanthanide such as La, Ce, Pr, Nd and/or other element, E designates Ti and/or Zr, where 0.01≤u≤0.1, M designates Fe and/or Cu, where 0≤z≤0.4, and 0.2≤w≤0.4, 0.3≤x≤0.5, 0.2≤y≤0.4, and 4.9≤v+w+x+y+z≤5.1.
