1. The
inhibition of cell polarization, reduce the heating effect and improve the rate
performance;
2. Reduce
the battery internal resistance, and decrease the circulation process of
dynamic resistance increase;
3. Improve
the consistency, increase the battery cycle life;
4. Improve
the adhesion of and active materials, reduce the pole piece manufacturing
cost;
5. Protect
collection of fluid from the electrolyte corrosion;
6. Improve
lithium iron phosphate, lithium titanate materials processing performance.
Coating thickness (Double side) A:
4~6um B: 2~3um
Conductive coating:
Using functional coatings for surface
treatment of battery conductive substrate is a breakthrough of technical
innovation, coated carbon foil/copper foil is to spread good nano conductive
graphite and carbon coated particles, fine and uniform coating on aluminum
foil/copper foil.Static electrical conductivity, it can provide an excellent
collection of active material micro electric current, which can greatly reduce
the positive/negative material and collector, the contact resistance between
the and can improve the adhesive ability between the two, can reduce the use
amount of binder, which creates an significantly improve the overall
performance of the battery.Can be divided into water based coating (water
system) and oil (organic solvent system) two types
