Carbon Coated Aluminum Foil for Battery Cathodes

This carbon coated aluminum foil is a high-performance current collector for lithium battery cathodes. It has a thin and uniform carbon conductive layer on the surface, which improves the electrical contact between the aluminum foil and cathode materials, reducing interface impedance. The carbon coating reduces voltage polarization during battery charge-discharge processes, improving energy efficiency and rate performance. It protects the aluminum foil surface from direct contact with electrolyte, reducing corrosion and improving battery cycle life. The foil maintains high mechanical strength and flexibility, adapting to battery manufacturing processes. It is suitable for high-rate lithium batteries, including power batteries for new energy vehicles and energy storage batteries requiring high efficiency and long life.
