    摘要: 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 IA/IB of 0.1 or greater in X-ray diffraction analysis using Cu—Kα radiation as an X-ray source, where IA is the strongest peak intensity that appears in the range of 2θ=31° to 33°, and IB is 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.

    摘要: Conductivity of a negative electrode is improved in an alkaline storage battery that uses as its negative electrode a hydrogen-absorbing alloy electrode employing a hydrogen-absorbing alloy containing at least a rare-earth element, nickel, magnesium, and aluminum, to sufficiently enhance the cycle life of the alkaline storage battery. The negative electrode of the alkaline storage battery uses a hydrogen-absorbing alloy electrode employing hydrogen-absorbing alloy particles containing at least a rare-earth element, nickel, magnesium, and aluminum. A surface layer is formed on the hydrogen-absorbing alloy particles, the surface layer having a weight ratio of aluminum to nickel less than that of the interior portion of the hydrogen-absorbing alloy. The weight ratio of aluminum to nickel in the surface layer is 0.015 or less.
