Customer ServicePE separators are thin, microporous membranes placed between the anode and cathode in a lithium-ion battery. Their primary function is to prevent physical contact between the electrodes while allowing ionic conductivity, ensuring efficient energy flow. Poor-quality separators can lead to thermal instability, internal short circuits, and even catastrophic failure.

Customer ServiceTypical separators used for lead–acid batteries throughout the world are listed in Table 2, together with the battery characteristics. Among these, the leaf-type SPG separator and the pocket-type PE separator are used in Japan according to the battery application, battery usage, and system requirements.
Thickness & Strength: The battery separator should be thin enough to facilitate the battery’s energy and power density and they should also have sufficient tensile strength to prevent stretching during the winding process.
When the battery is charging the ions moves from cathode to anode and when the battery gets discharged the ions will move in the reverse direction. The separator controls the number of ions moving between the positive and negative terminal and hence it is responsible for the leakage of ions (self-discharge) when the battery is ideal.
Another important part of a battery that we take for granted is the battery separator. These separators play an important role in deciding the functionality of the battery, for examples the self-discharge rate and chemical stability of the battery are highly dependent on the type of separator used in the battery.
In Japan, due to the decrease in vibration of the battery caused by the improvement in road conditions and the popularisation of the MF battery, the envelope-type separator is required for expanded-type calcium electrodes. The application of this separator has spread to about 70% in batteries for common passenger cars.
At present, the separators are developed from various types of materials such as cotton, nylon, polyesters, glass, ceramic, polyvinyl chloride, tetrafluoroethylene, rubber, asbestos, etc... In conditions like rising in temperature, the pores of the separator get closed by the melting process and the battery shuts down.
