Patent ID: 7935305

Claim:
An anode for a nickel-hydrogen rechargeable battery comprising, as anode materials: a hydrogen storage alloy (a) of a composition represented by the formula (1), wherein said alloy has a substantially single phase structure, and crystals of said alloy has an average long axis diameter of 70 to 160 μm: RNi x Co y M z (1) wherein R stands for one or a mixture of rare earth elements including yttrium, M stands for Mg, Al, Mn, Fe, Cu, Zr, Ti, Mo, W, B, or mixtures thereof, x satisfies 3.7≦x≦5.3, y satisfies 0.1≦y≦0.5, z satisfies 0.1≦z≦1.0, and 5.1≦x+y+z≦5.5, a hydrogen storage alloy (b) of a composition represented by the formula (1), wherein said alloy has a substantially single phase structure, and crystals of said alloy have an average long axis diameter of not smaller than 5 μm and smaller than 30 μm, and an electrically conductive material.
