摘要

The present invention relates to a method for manufacturing an alkaline secondary battery having improved utilization efficiency of a positive electrode, a large current discharge characteristic, discharge capacity, and capacity recovery ratio after being left unattended. The method for producing an alkaline secondary battery consisting of a positive electrode, a negative electrode, and an alkaline electrolyte containing a nickel compound and a cobalt compound includes an initial charge in a charging process that supplies a current (I) (mA) that satisfies the following inequality (1). Performing the steps.;50 (T × C 2 ) / (I × S) 2000 ①;Where C is the electrochemical capacity (mAh) of the cobalt compound contained in the positive electrode and is calculated based on the electrochemical equivalent of the cobalt compound, T is the temperature (° C.) when the charging process is performed, and S is It is the area (cm 2) of the positive electrode.
