Li-ion battery PP separator/film/membrane/diaphragm manufactured by dry and uniaxial stretching process, equipped with high precision testing instruments, using high purity PP material and advanced production technology. separator film in thickness of 12-60 microns with different specifications, widely used in Li-ion power batteries, Li-ion energy storage battery and Li- ion digital product battery
Advantages:
1. High safety: Multilayer membrane efficiently reduces the safety hazards (crystal point, holes…) which
are found as defects on single layer membrane; low TD & MD shrinkage; Perfect heat resistance and
anti-oxidant; High puncture strength & mechanical strength , suitable for high/low voltage system.
2. 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.
3. Excellent air permeability: High porosity, high air-permeability, low sinuosity, suitable for high rate
discharging of electric vehicle Li-ion battery.
4. Various products: Basic separator, Ceramic coated separator, Polymer coated separator,
Multifunctional hybrid coating separator, Multi-layer functional coated separator.
