Active lithium excitation method and application of lithium battery with supplemented lithium pole piece

The invention discloses an active lithium excitation method for a lithium battery with a supplemented lithium pole piece, which comprises the following steps of: 1, placing the lithium battery with the supplemented lithium pole piece in an incubator, and standing for a preset time length, so that the internal and external temperature difference of the lithium battery is zero; 2, in the use process of the lithium battery, counting the charge-discharge cycle times of the lithium battery in real time; 3, presetting a corresponding relationship between a plurality of preset different charge-discharge cycle times of the lithium battery and a plurality of systems; 4, detecting whether the charge-discharge cycle index of the lithium battery reaches a preset charge-discharge cycle index or not in real time, and performing charge-discharge cycle operation on the lithium battery once according to the system corresponding to the preset charge-discharge cycle index when the charge-discharge cycle index reaches the preset
