Method for identifying and coping with false death of electrode of silicon-based high-capacity lithium battery

The invention provides a method for identifying and coping with false death of an electrode of a silicon-based high-capacity lithium battery. According to the method, the false death of the electrode of the silicon-based high-capacity lithium battery is identified and dealt with by changing a charging and discharging voltage window. Generally, the silicon-based high-capacity lithium battery is unavoidable to be partially charged and discharged, so that an electrode is subjected to false death, and then the capacity of the battery is quickly reduced. According to the method, complete charging and discharging are recovered by resetting, namely, changing part of the charging and discharging voltage window, specifically, if the battery capacity is sharply increased and recovered to the initial capacity, it is considered that false dead of the electrode occurs; and if the battery capacity does not change obviously, it is considered that no electrode false death occurs. In addition, in order to solve the problem of
