ABSTRACT:
An alkaline storage battery system according to an aspect of the present invention, with which a partial charging-discharging is performed, includes an alkaline storage battery10including an electrode group having a nickel positive electrode11, a hydrogen storage alloy negative electrode12, a separator13; an alkaline electrolyte; and an outer can14accommodating the electrode group and the alkaline electrolyte, and further includes a partial charge-discharge control unit for controlling charging-discharging of the battery10. In addition, zinc (Zn) is added to nickel hydroxide that is a main positive electrode active material in the nickel positive electrode11with an addition amount of 5% by mass or less with respect to the mass of nickel in the positive electrode active material. The concentration of the alkaline electrolyte is 6.5 mol/L or less and the content of lithium in the alkaline electrolyte is 0.3 mol/L or more.
