What is the battery separator?

    Battery separator refers to a layer of separator material between the positive electrode and the negative electrode of the battery. It is a very important part of the battery and has a direct impact on the safety and cost of the battery. Its main function is to isolate the positive and negative electrodes and prevent the electrons in the battery from passing through freely, so that the ions in the electrolyte can pass freely between the positive and negative electrodes.

    The ion conduction capacity of the battery separator is directly related to the overall performance of the battery. Its function of isolating the positive and negative electrodes enables the battery to limit the rise of current in the case of overcharge or temperature rise, prevent explosion caused by short circuit of the battery, and has the function of microporous self closing protection, which plays a role in safety protection for the battery users and equipment.
