Abstract
The structure and hydrogen-absorbing characteristics of four new chemically-prepared alloys of the type LaNi5-x-yMxMy′(M=Co, Cu; M′=Mn; 0<x+y<5) were investigated. These alloys are easy to be activated, and have relatively high hydrogen capacity. A linear coorelation exists between the hydride stability and the cell volume of the La-Ni-Co-Mn alloys. XPS studies on LaNi4Co0.5Mn0.5 indicated that metallic nickel and cobalt exist on the surface, which may be responsible for the good hydrogen-absorbing activity.
