What use does the separator play in lithium batteries

The diaphragm is an important part of the lithium battery and has always been used as a support and protection effect in the lithium battery. The quality of the separator's raw materials can also determine the function of the battery. The effect of the separator in the battery is mainly as follows. 1. Isolate the positive and negative north and south poles. The separator material must have electronic isolation to ensure mechanical isolation between the north and south poles. Beware of touching the positive and negative poles. If the north and south poles touch each other, it will cause an internal short circuit of the lithium battery, causing damage to the battery. There was an explosion and fire work. 2. It can moisturize the electrolyte, which greatly reduces the loss of the electrolyte, and also has good permeability during the transmission of lithium ions. The raw material of the diaphragm requires strong permeability. 3. If the temperature of the lithium battery is too high, the diaphragm will have an automatic shutdown protection function.
