Lithium ion Battery Separator Film Polypropylene Separator/Membrane/Diaphragm

Tianhong corporation has advanced international production lines for Lithium battery separator by dry and uniaxial stretching process, equipped with high precision testing instruments, using high purity PP material and advanced production technology, mainly produce Li-ion battery separator film in thickness of 12-60 microns with different specifications, which is widely used in Li-ion power batteries, Li-ion energy storage battery and Li- ion digital product battery.

Advantages of Lithium Battery Separator:

1. High safety: Multi-layer 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.

2. Good uniformity: Using popular dry & uniaxial stretching process, insure the pore sizes uniformity and well distributed on membrane. The separator has multi-layer 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, Multi-functional hybrid coating separator, Multi-layer functional coated separator.
