Abstract:
A hydrogen-absorbing alloy consisting essentially of a composition expressed by the following general formula:Ti.sub.x V.sub.y Mn.sub.z1 Fe.sub.z2,where z=z1+z2, x+y+z=100, x/z=0.25 to 2.0, x: 14 to 47, y: 16 to 40, and z: 31 to 64 in terms of the atomic number ratio;the phase of a body-centered cubic structure which is at least 50% in terms of the phase fraction;and the lattice constant which is 0.2950 nm to 0.3100 nm.
