  What are the required characteristics of battery separator technology?

  Comparative requirements and characteristics of the process line Dry method: Stretch porogen method: Utilizes crystallization defects in crystallizable polymer materials; uses process control and uses tensile external force to cause crystallization defects to break into holes; utilizes polypropylene, polytetrafluoroethylene , polyethylene and other materials with high crystallinity, representative processes: American Celgard and Japanese Udo wet method: also called phase separation method or thermally induced phase separation method, small molecules with high boiling point are added to polyene as porogens. Heating and melting into a uniform system, then cooling to cause phase separation, and after stretching, using organic solvents to extract small molecules, can prepare interpenetrated microporous membrane materials. It is suitable for a wide range of materials. Representative processes: Japan's Asahi Kasei, Tosen, and Nitto and Entek of the United States
