Abstract
A hydrogen-absorbing alloy electrode for an alkaline storage cell, the electrode including a hydrogen-absorbing alloy expressed by a composition formula ReBxMy, wherein Re is at least one element selected from a group consisting of rare earth elements and alkali earth elements, B is boron, and M is at least one element selected from a group consisting of Ni, Co, Mn, Al, Cr, Fe, Cu. Sn, Sb, Mo, V, Nb, Ta, Zn, Zr and Ti. The alloy consists essentially of an RM.sub.y main metal phase, and a subordinate boron-containing phase, such as a compound phase of boron and a IV-a, V-a, or VI-a group metal.
