Overcharging will cause battery explosion

Lithium batteries generally have safety protection circuits and various safety devices to ensure that the battery circuit is automatically cut off in case of overcharge, discharge and short circuit; High internal pressure of the battery will also trigger the pressure reduction of the exhaust device; If the battery temperature is too high, the hot melt protection device will be triggered to stop the electrochemical reaction of the battery. Therefore, unless there is a quality problem, the battery will not explode due to charging for a long time. However, if you do not unplug the power after fully charged, the battery will remain fully charged. Although it will not explode, it will accelerate the loss of battery capacity. In addition, there are rumors that answering the phone while charging will cause an explosion. Lu Jianguo said that this statement is untenable. If there is such a danger, the product will be set up with a program that does not connect to the phone when charging. However, from the perspective of health, the electric wire will limit the range of activity of the user. Receiving and making calls while charging may cause the user to stay in one place for a long time, resulting in excessive muscle tension. Therefore, it is recommended to unplug the power supply and call again. When charging, do not cover anything on the battery or put it on the bed to avoid fire.
