The separator is a key component in battery manufacturing, mainly used in lithium-ion batteries, sodium-ion batteries, and other electrochemical energy storage devices. Its main function is to isolate the positive and negative electrodes, prevent the internal short circuit of the battery, and allow ions to pass through to ensure the normal operation of the battery.
