<p><P>PROBLEM TO BE SOLVED: To provide a hydrogen storage alloy electrode and a nickel hydrogen storage battery which are not less than in discharge capacity compared with the conventional ones, and are superior in charging acceptance performance when quick charging is performed, and in charge discharge cycle performance. <P>SOLUTION: Hydrogen storage alloy powder is applied which has a CaCu<SB>5</SB>type crystal structure as active material for a hydrogen storage alloy electrode, and is composed of MmMgNiCoMnAl, and at least in which the minute separation phases composed of MgNiCoMnAl alloy phases exist dispersed. Moreover, it is desirable that hydrogen storage alloy powder having surface layers composed of an alloy of Ni and Co, be applied on the powder surfaces. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
