Abstract
A method of manufacturing a hydrogen-absorption alloy electrode which comprises particles of a hydrogen-absorption alloy that comprises a rare earth element, Ni, Co and Al. The method comprises subjecting the hydrogen-absorption alloy particles to an alkaline treatment in a 10 to 50 weight % NaOH solution at 60 to 140° C. for 0.5 to 5 hours such that on the surface of the particles (amount of Al on surface/amount of Al in alloy)<(amount of Co on surface/amount of Co in alloy).
