The lead-acid battery is one of the most important DC power sources in a substation, and it undertakes the important responsibility of ensuring the normal operation of a power system. To prolong the battery’s cyclic life and respond to environmental protection policies, the repairing technology for substation decommissioned batteries is gradually becoming popular. A low-cost and convenient repairing method with repair solution was selected, and the electrochemical working environment for the battery’s negative electrode was designed and simulated based on the cyclic voltammetry method. The effects of different types of chemical agents on the charge and discharge capacity of negative electrode were studied, and orthogonal experiments were used to screen out composite activators that have excellent improvement effects on the charge and discharge capacity of negative-electrode. The results are of signify-cance for activating and repairing substation decommissioned lead-acid batteries.
