15+1+1µm Carbon Coated Aluminum Foil

15+1+1µm Carbon Coated Aluminum Foil is a composite foil fabricated by depositing a double conductive carbon layer on the surface of electronic aluminum foil; it acts as a positive current collector in batteries. It supports lower resistance, higher adhesion of active materials, and prevents oxidation and corrosion of the aluminum foil to extend the battery life cycle and improve battery performance.
