Lithium ion Battery Diaphragm 2500 high Rate Single-Layer PP Diaphragm（25um*60mm*100m）

Thickness: 25um Width: 60mm Length: 100m Air permeability: 200sec/100cc Thermal shrinkage TD (90 ° C/h): ≤ 0% Heat shrinkable MD (90 ° C/h) |: ≤ 5% Tensile strength (Kg/cm2): MD ≥ 773; TD≥78 Puncture strength (g): ≥ 200 Porosity (%): 55 2500 single-layer PP diaphragm characteristics: Production by dry stretching process Excellent resistance to acid, alkali and most chemicals Consistent pore structure with high chemical and thermal stability Ideal for various battery type applications Excellent oxidation resistance, ensuring excellent cycle and trickle charging performance Horizontal (TD) "zero" shrinkage reduces internal short circuits and improves high temperature dimensional integrity

• The diaphragm is an important part of the lithium ion battery. It is located between the positive and negative electrodes inside the battery, ensuring that lithium ions pass through and hindering electronic transmission. The performance of the separator determines the interface structure and internal resistance of the battery, which directly affects the capacity, cycle and safety of the battery. The separator with excellent performance plays an important role in improving the overall performance of the battery.
• 2500 is PP single layer film. The single-layer PP diaphragm can provide better magnification performance, and can maintain stability in a wider temperature range, so it is also very suitable for the application of electric vehicles (HEV).
