Abstract
A hydrogen-absorbing alloy for a negative electrode in an alkaline storage battery includes a first hydrogen-absorbing alloy and a second first hydrogen-absorbing alloy. The first hydrogen-absorbing alloy contains at least a rare-earth element, Mg, Ni, and Al, and has an intensity ratio I/Iof 0.1 or greater in X-ray diffraction analysis using Cu—Kα radiation as an X-ray source, where Iis the strongest peak intensity that appears in the range of 2θ=31° to 33°, and Iis the strongest peak intensity that appears in the range of 2θ=40° to 44°. The second hydrogen-absorbing alloy has a Co content greater than that of the first hydrogen-absorbing alloy.
