13+0.8+0.8 Carbon Coated Battery Cathode Aluminum Foil

13+0.8+0.8 Carbon Coated Battery Cathode Aluminum Foil is a composite material based on pure aluminum foil, where a conductive carbon layer is deposited onto its surface via gravure coating technology. It is primarily used as the positive current collector in lithium-ion batteries. This material reduces battery contact resistance, enhances adhesion of conductive active materials, prevents oxidation and corrosion of the aluminum foil, improves cell performance consistency, extends battery cycle life, and enhances safety.
