Advantages of Carbon Coated Aluminum Foil in Lithium Battery Applications

1. Suppress battery polarization, reduce thermal effects, and improve rate performance; 2. Reduce the internal resistance of the battery and significantly reduce the dynamic internal resistance increase during the cycling process; 3. Improve consistency and increase battery cycle life;

4. Improve the adhesion between the active substance and the collector, and reduce the manufacturing cost of the electrode; 5. Protect the fluid collector from corrosion by the electrolyte;

6. Improve the processing performance of lithium iron phosphate and lithium titanate materials.

Coating double-sided thickness: Type A 4-6 μ m. B-type 2-3 μ M.

Conductive coating

The use of functional coatings for surface treatment of battery conductive substrates is a groundbreaking technological innovation. Carbon coated aluminum foil/copper foil refers to the uniform and delicate coating of dispersed nano conductive graphite and carbon coated particles on the aluminum foil/copper foil. It can provide static conductivity of * * *, collect micro currents of active substances, significantly reduce the contact resistance between positive/negative electrode materials and current collectors, and improve the adhesion ability between the two. It can reduce the use of adhesives, thereby significantly improving the overall performance of the battery. There are two types of coatings: water-based (aqueous system) and oily (organic solvent system).
