  • INQUIRY

The PE separator for lithium batteries is a microporous film made of polyethylene (PE) as the base material and is one of the key components of lithium batteries. It is located between the positive and negative electrodes of the battery, which can prevent direct contact between the two electrodes and short circuit. Meanwhile, its micro-porous structure allows lithium ions to pass freely, ensuring the normal charging and discharging of the battery. PE separators have the advantages of good chemical stability, low cost and controllable porosity, which can effectively enhance the energy density and cycle life of batteries. However, its heat resistance is relatively weak and it is prone to deformation at high temperatures. Therefore, in practical applications, PE separators are often modified by coating them with materials such as ceramics to enhance their thermal stability and mechanical strength, thereby better meeting the performance requirements of lithium batteries.
