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 batteryincluding an electrode group having a nickel positive electrode, a hydrogen storage alloy negative electrode, a separator; an alkaline electrolyte; and an outer canaccommodating the electrode group and the alkaline electrolyte, and further includes a partial charge-discharge control unit for controlling charging-discharging of the battery. In addition, zinc (Zn) is added to nickel hydroxide that is a main positive electrode active material in the nickel positive electrodewith 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.
