ABSTRACT:
A hydrogen absorbing alloy is disclosed for use as the negative electrode in alkaline batteries. The general formula of the alloy is AB.sub.x M.sub.y, wherein A is selected from the rare earth element La or a mischmetal thereof; B is selected from the group consisting of Ni, Fe, Mn, Cr, Cu, Co, and mixtures thereof; M is selected from the group consisting of Al, In, Zn, Sn, Ga, Si, Ge, Bi, and mixtures thereof; 4.5.ltoreq.x.ltoreq.5.5; and 0.3<y.ltoreq.0.6. This alloy has a longer cycle life, along with larger capacity and better reactivity.
