Hydrogen storage alloy electrode
摘要:
The present invention provides a hydrogen storage alloy electrode high in capacity and exceptional in cycle life characteristic by improving a conventional V-based hydrogen storage alloy of a body-centered cubic structure. The electrode comprises particles of a hydrogen storage alloy represented by the general formula V 1-a-b-c-d Ti a Cr b M c L d , wherein M is at least one element selected from the group consisting of Mn, Fe, Co, Cu, Nb, Zn, Zr, Mo, Ag, Hf, Ta, W, Al, Si, C, N, P and B, and L is at least one element selected from the group consisting of Y and rare earth elements, and 0.2≤a≤0.5, 0.1≤b≤0.4, 0≤c≤0.2 and 0
