PURPOSE:To increase the occluding and releasing amount of hydrogen and repress alloy to be powdered by using, as a hydrogen occluding material of hydrogen occlusion electrode, alloy in which at least one kind of element selected from specific elements is contained as Ti-Fe alloy serving as a base. CONSTITUTION:Alloy, in which at least one kind of element selected from A1, Si, V, Cr, Mn, Ni, Co, Cu, Zn, Y, Zr, Nb, Mo, Hf, Ta, La, and alkaline earth metals is contained as Ti-Fe alloy serving as base, is used as a hydrogen occlusion electrode of metal-hydrogen alkaline battery. This obtained alloy occludes and releases hydrogen in much amount, with is crystal lattice less deformed. Therefore, using the alloy as a hydrogen occlusion material realizes increase of discharge capacity and repression of alloy powdered, with the cell maintaining a large capacity over a long period. |
