ELECTROCHEMICAL APPARATUS AND CONTROL METHOD THEREFOR, ELECTRONIC DEVICE, AND STORAGE MEDIUM

Provided in an embodiment of the present application are an electrochemical apparatus and a control method therefor, an electronic device and a storage medium. A negative electrode active material of the electrochemical apparatus comprises a first active material and a second active material, the capacity per gram of the first active material being smaller than that of the second active material, and a discharge working voltage range of the first active material comprising a first voltage range which is not larger than the upper limit of a discharge working voltage of the second active material. The electrochemical apparatus operates at a first discharge cutoff voltage and a first charge cutoff voltage in a first time period, the electrochemical apparatus operates at a second discharge cutoff voltage and a second charge cutoff voltage in a second time period, and the first discharge cutoff voltage and the second discharge cutoff voltage are both within the first voltage range; and the first discharge cutoff v
