Alkaline secondary battery manufacturing method, alkaline secondary battery positive electrode, alkaline secondary battery, and a method of manufacturing an initially charged alkaline secondary battery

摘要

Disclosed is a method of manufacturing an alkaline secondary battery improved in the positive electrode utilization, the large-current discharge characteristic, the discharge capacity, and the capacity recovery ratio after storage. This method of manufacturing an alkaline secondary battery comprising a positive electrode containing a nickel compound and a cobalt compound, a negative electrode and an alkaline electrolyte, the method comprising the step of performing initial charging which comprises a charging process of supplying a current I (mA) satisfying the following Inequality (1):50<(TxC2)/(IxS)<2000(1)where C is a electrochemical capacity (mAh) of the cobalt compound contained in the positive electrode, which is calculated on the basis of a electrochemical equivalent of the cobalt compound, T is a temperature ( DEG C.) at which the charging process is performed, and S is an area (cm2) of the positive electrode.
