    摘要： [Problem] To suppress increases in the resistance of nickel positive electrodes and assure sufficient battery capacity even after repeated pulse charging and discharging cycles with a large current. [Solution] This alkaline storage battery (10) contains aluminum (Al) in a hydrogen storage alloy negative electrode (12) and also includes Al in a nickel positive electrode (11). In a state where a prescribed charging and discharging cycle has completed, the Al content in the nickel positive electrode (11) is 0.25% by mass or greater of that in the positive electrode active material, and in powder x-ray diffraction of the positive electrode active material using Cu—Kα, the half-width of the (101) plane peak for Ni(OH)2 is controlled so as to be 0.5 (°/2θ) or greater.
