Ultra-high heat resistance
It can withstand high temperature and super durability, greatly improving the safety of high energy density batteries, among which the nanofiber diaphragm can withstand 180°C, solvent type aramid diaphragm can withstand 200°C.
High thermal stability and low thermal shrinkage
Good thermal stability, low thermal shrinkage, minimize the occurrence of thermal runaway.
High liquid absorption rate and retention rate
High electrolyte retention, can improve diaphragm infiltration.
Excellent puncture resistance
Good oxidation resistance, acid and alkali resistance and puncture resistance.
It can improve the bonding property between the positive and negative electrodes of the diaphragm and reduce the deformation of the cell.
High strength and excellent breathability
Uniform porosity, high tensile strength, good air permeability.
We have a wide range of coating products with excellent performance, including ceramic coated diaphragm (alumina, Boehmite, nanofiber, magnesium hydroxide), polymer coated diaphragm (PVDF, Aramid), multilayer functional mixed coated diaphragm (ceramic +PVDF, ceramic + aramid, etc.).
Support multiple customization
The thickness of the product can be adjusted flexibly between 5μm and 30μm (including the thickness of the base film), which can be customized according to customer and market demand.
