Advantages:
- High safety: Multilayer membrane efficiently reduces the safety hazards (crystal point, holes…) which are found as defects on single layer membrane; No TD shrinkage, , low MD shrinkage; Perfect heat resistance and anti-oxidant; High puncture strength & mechanical strength , suitable for high/low voltage system.
- Good uniformity: Using popular dry & uniaxial stretching process, insure the pore sizes uniformity and well distributed on membrane. The separator has multilayer structure with better thickness uniformity to improve Li-ion battery cycle life.
- Excellent air permeability: High porosity, high air-permeability, low sinuosity, suitable for high rate discharging of electric vehicle Li-ion battery.
- Various products: Basic separator, Ceramic coated separator, Polymer coated separator, Multifunctional hybrid coating separator, Multi-layer functional coated separator.
