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.
