An alkaline rechargeable battery (2) comprises an electrode assembly (22) formed of a positive electrode (24) and a negative electrode (26) stacked with a separator (28) interposed between and an alkaline electrolyte, wherein the positive electrode (24) holds a positive electrode mixture containing positive-electrode active material particles (36), each comprising of a base particle (38) formed primarily of nickel hydroxide, coated with a conducive layer (40) of a Co compound containing Li, and a positive-electrode additive (50) containing aluminum hydroxide, distributed between the positive-electrode active material particles, where the amount U of the positive-electrode additive (in parts by weight) relative to 100 parts by weight of the positive-electrode active material particles satisfies 0.01‰¤U<1.5, and wherein Li is present within the alkaline rechargeable battery (2), where the total amount of Li present within the alkaline rechargeable battery (2), in terms of weight of LiOH per unit positive-electrode capacitance 1Ah, is between 20 and 30 (mg/Ah). |
