electric vehicle battery Aluminum Foil

12+0.6+0.6µm Carbon Coated Aluminum Foil is a composite foil fabricated by depositing a conductive carbon layer on the surface of electronic aluminum foil substrate, primarily used as a positive current collector in lithium-ion batteries. By reducing contact resistance, enhancing adhesion of active materials, and preventing oxidation and corrosion of the aluminum foil, it significantly improves battery cycle life, safety, and cell consistency.
