Battery coated separator series |
|
The self-developed bio-based polyamide coating material is combined with various adhesives and combined with ceramic or Boehmite layers. It is treated by water-based or oil-based coating process technology and adheres to the surface of base films produced by different methods. It can significantly improve the high-temperature stability of new energy batteries and enhance their safety. It is suitable for high-performance battery products, and material solutions can be customized. | |
High security The oil-based aramid coated separator still retains elasticity and toughness after being exposed to 200℃ for 1 hour. The battery assembled with aramid separator passed through the 150℃ heat box. The pass rate of battery thermal needling is high. |
