Abstract
A method for detecting a lithium separation phenomenon of a battery of a terminal device is provided. The method includes detecting a working state of the battery, and collecting a first voltage of the battery when the working state of the battery is the resting state. The method further include collecting a second voltage of the battery when the battery is left to stand for a preset period of time, and determining whether the lithium separation phenomenon has occurred according to the first voltage and the second voltage. The implementation of the application can detect whether the lithium separation phenomenon has occurred in the battery and trigger a protection circuit of the battery in time when the lithium separation phenomenon has occurred in the battery.
