Product description
The coated battery separator is based on the traditional polyolefin separator. The thermal stability of the separator is improved by coating high-purity nano-alumina or boehmite and other materials on one or both sides, with better high-temperature resistance and better liquid absorption and retention performance. It is mainly used in power battery and multiplier battery, which can greatly improve the safety and stability of lithium-ion battery.
Coated battery separator
Designed for safety and high temperature resistance
Ultra-high heat resistance
It can withstand high temperature and super durability, and greatly improve the safety of high energy density batteries. The nanofiber membrane can withstand 180 ° C, and the solvent-based aramid membrane can withstand 200 ° C.
Strong thermal stability and low thermal shrinkage
Good thermal stability, low thermal shrinkage, minimize the occurrence of thermal runaway.
High liquid absorption rate and liquid retention rate
High electrolyte retention can improve the permeability of membrane.
Good puncture resistance
It has better anti-oxidation, acid-base resistance and puncture resistance.
High adhesion
It can improve the bonding performance between the positive and negative poles of the diaphragm and the core, and reduce the deformation of the core.
High strength and excellent ventilation
Uniform pores, high tensile strength and excellent permeability.
Variety
It has a wide range of coating and coating products with excellent performance, including ceramic coating separator (alumina, boehmite, nanofiber, magnesium hydroxide), polymer coating separator (PVDF, aramid), multilayer functional mixed coating separator (ceramic+PVDF, ceramic+aramid, etc.).
Support diversified customization
The product thickness can be within 5 μ M to 30 μ Flexible adjustment (including base film thickness) can be made according to customer and market demand.
