NOVELTY - An alkaline storage battery comprises electrode group which consists of hydrogen storage alloy negative electrode (12) containing hydrogen storage alloy as negative electrode active material and nickel positive electrode (11) containing nickel hydroxide as positive electrode active material, and separator (13) in armored can (17) with alkali electrolyte solution. Zinc addition amount is less than or equal to 8 mass% with respect to nickel mass in positive electrode active material. The alkali electrolyte solution contains compound chosen from tungsten compound, molybdenum compound and niobium compound.    USE - Alkaline storage battery for alkaline storage battery system (claimed) and hybrid electric vehicle.    ADVANTAGE - The battery has high output (regeneration characteristic) and highly-durable performance at low cost.    DETAILED DESCRIPTION - An alkaline storage battery comprises electrode group which consists of hydrogen storage alloy negative electrode (12) containing hydrogen storage alloy as negative electrode active material and nickel positive electrode (11) containing nickel hydroxide as positive electrode active material, and separator (13) in armored can (17) with alkali electrolyte solution. Zinc addition amount is less than or equal to 8 mass% with respect to nickel mass in positive electrode active material of formula LaxReyMg1-x-yNin-aMa. The alkali electrolyte solution contains compound chosen from tungsten compound, molybdenum compound and niobium compound with 0.5-2 mass% addition amount with respect to mass of positive electrode active material.    M=Al, Co, Mn and Zn; and    x divide by y= greater than or equal to 0.4.    An INDEPENDENT CLAIM is included for an alkaline storage battery system which carries out partial charge-and-discharge control of the alkaline storage battery.
