Patent ID: 7544442

Claim:
A hydrogen-absorbing alloy electrode comprising: a first hydrogen-absorbing alloy containing at least a rare-earth element, magnesium, nickel, and aluminum, and cobalt in an amount of 2.0 weight % or less, and having an intensity ratio I A /I B of 0.1 or greater in X-ray diffraction analysis using Cu—Kα radiation as an X-ray source, where I A is the strongest peak intensity that appears in the range of 2θ=31° to 33°, and I B is the strongest peak intensity that appears in the range of 2θ=40° to 44°; and a second hydrogen-absorbing alloy having a CaCu 5 crystal structure and a cobalt content greater than the first hydrogen-absorbing alloy, and being added to the first hydrogen-absorbing alloy, wherein the second hydrogen-absorbing alloy has a smaller average particle diameter than that of the first hydrogen-absorbing alloy.
