Key Advantages
- High Safety: Multilayer membrane efficiently reduces safety hazards (crystal point, holes) 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 systems.
- Good Uniformity: Using popular dry & uniaxial stretching process, ensures pore size uniformity and well-distributed membrane pores. Multilayer structure with better thickness uniformity improves 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 batteries.
- Various Products: Basic separator, Ceramic coated separator, Polymer coated separator, Multifunctional hybrid coating separator, Multi-layer functional coated separator.
