Battery capacity improving method and device, electronic equipment and storage medium

The invention provides a battery capacity improving method and device, electronic equipment and a storage medium. The method comprises the following steps: performing multiple times of pulse discharge on a to-be-processed battery, so that the state of charge of the to-be-processed battery after multiple times of pulse discharge is reduced to a target state of charge to improve the capacity of the to-be-processed battery; wherein the charge state of the to-be-processed battery before multiple times of pulse discharge is greater than a preset charge state, the interval time of two adjacent times of pulse discharge in the multiple times of pulse discharge process is not less than a preset duration, and the battery is in a standing state in the time interval of two adjacent times of pulse discharge in the multiple times of pulse discharge process; and the discharge rate of multiple times of pulse discharge is not less than 0.3 C. According to the embodiment of the invention, the to-be-processed battery is subjected to multiple times of pulse discharge, and each pulse discharge can create an environment in which lithium ions are relatively deficient, so that lithium is effectively removed from the tip of a lithium dendrite, and the battery capacity is improved.
