ABSTRACT:
A secondary battery operating method for charging and discharging a secondary battery using zinc as the negative electrode active material. After the termination of the normal discharge, direct current supply means is connected to the secondary battery in opposite polarity relation with each other and the secondary battery is reverse charged in a polarity opposite to the normal polarity. As a result of this reversed charge, the zinc remaining on the negative electrode after the termination of the normal discharge is completely dissolved into the electrolyte. If necessary, the energy stored in the secondary battery after the termination of the normal discharge is regenerated during the reversed charge.
