Abstract
This invention relates to an active material of hydrogen storage alloy electrode. The composition of the active material has a formula: Mm Ni.sub.5-x-y-z-u A.sub.x B.sub.y C.sub.z D.sub.u ; wherein Mm is mischmetal; A=Mn, Sn, or V; B=Cr, Co, Ti, Nb, Zr, or Si; C=Al, Mg, or Ca; D=Li, Na, or K; 0.ltoreq..times..ltoreq.0.95; 0.ltoreq. y.ltoreq. 1; 0.ltoreq. z.ltoreq. 0.7; and 0.1.ltoreq. u.ltoreq. 0.9. Alternatively, the composition may be of the formula: Ti.sub.2 Ni.sub.1-u Du; wherein D=Li, Na, or K; and 0.04.ltoreq. u.ltoreq. 0.9. This active material can relieve the alkali metal ions M.sup.+ continuously in charge-discharge process of the alkali batteries, increase the concentration of MOH within the battery, take effect in protecting the cathode and the anode validly, and improve the cycle life and the discharge capacity of the battery.
