Document Type and Number:
WIPO Patent Application WO/2015/068331
Kind Code:
A1
Abstract:
Provided is an electrode alloy powder useful in obtaining a nickel-hydrogen storage cell exhibiting high storage capacity and reduced self-discharge. This alloy powder comprises a mixture containing: particles of a first hydrogen-absorbing alloy having an AB5-type crystal structure; and particles of one or more types of a second hydrogen-absorbing alloy selected from a group consisting of a hydrogen-absorbing alloy (a) having an AB2 crystal structure, and a hydrogen-absorbing alloy (b) having an AB3 crystal structure. Therein, the content of the first hydrogen-absorbing alloy in the mixture constitutes more than 50 mass%.
