<p>An anode active material realizing an alkali storage battery high in discharge voltage and excellent in high-rate discharge characteristic, an anode including the same, and an alkali storage battery are disclosed. The anode active material is made of a nickel hydroxide powder. The nickel hydroxide is a solid solution containing magnesium. The content of magnesium in the nickel hydroxide is 2 to 7 mole% based on all the metal elements contained in the nickel hydroxide. The tap density of the nickel hydroxide is 1.9 g/cm3 or more. The half-width of the peak attributed to the (101) face near 2υ=37 to 40° in the power X-ray diffraction pattern of the nickel hydroxide by CuK α-ray irradiation is 0.7 to 1.2°. The content of sulfate ions contained in the nickel hydroxide is 0.5 weight or less.</p> |
