INQUIRY

The PE separator for lithium batteries is made of polypropylene material and features a micro-porous structure. It can isolate the positive and negative electrodes to prevent short circuits while allowing lithium ions to pass through. It features excellent chemical stability, mechanical strength and high-temperature resistance (melting point approximately 160-170℃), and is commonly used as a single-layer film or in combination with PE (such as a three-layer structure of PP/PE/PP) to enhance puncture strength and thermal stability. It is widely used in power and energy storage batteries. Through the biaxial stretching process, the pore size and porosity are controlled to ensure the battery's cycle life and safety.
