摘要： An alkaline storage battery system includes an alkaline storage battery 10 including an electrode group having a hydrogen storage alloy negative electrode 11 using a hydrogen storage alloy as a negative electrode active material, a nickel positive electrode 12 using nickel hydroxide as a main positive electrode active material, and a separator 13, and further including an alkaline electrolyte, in an outer can 17, and is performed partial charge-discharge control. Here, the hydrogen storage alloy has at least A5B19 type crystal structure, and a stoichiometric ratio (B/A) representing a molar ratio of B component to A component in the A5B19 type crystal structure is 3.8 or more. According to the alkaline storage battery system of the present invention, an alkaline storage battery system that ensures high power, reduces the used amount of the hydrogen storage alloy significantly, and is controlled partial charging-discharging is obtained.
