  • Charging method for electrochemical device, electronic device and readable storage medium
    Patent number: 12206078
    Abstract: A charging method for an electrochemical device includes the following steps: in a first cycle stage, a charging stage of the first cycle stage has a first cut-off voltage; and in a second cycle stage, a charging stage of the second cycle stage has a second cut-off voltage, and the second cut-off voltage is less than the first cut-off voltage. According to the charging method for an electrochemical device, an electronic device, and a readable storage medium provided in the present application, the risk of cyclic gas generation of the electrochemical device can be effectively prevented, and the service life of the electrochemical device can be improved.
    Type: Grant
