Method for pre-charging and pre-discharging lead acid battery adopting composite anode

The invention relates to a method for pre-charging and pre-discharging a lead acid battery adopting a composite anode, and belongs to the field of electrochemical power. The method comprises the following step of: continuously performing 1 to 20 charging and discharging cycles on the battery before container formation is officially started, wherein the charging and discharging cycle is specifically formed by 1 to 40min charging and discharging or 1 to 20min reverse charging realized by the low current of 0.01 to 0.03C. The method aims to deposit lead on a capacitance layer and an interface of an anode body of the lead acid battery as much as possible to make the bonding of the capacitance layer on the surface of the anode body firmer and avoid the stripping of the capacitance layer due to gas evolution in the running process of the battery, thereby improving the performance of the battery.
