Graphene on Aluminum Foil

This product is a novel current collector with a uniform graphene coating on the surface of aluminum foil. Utilizing the excellent conductivity and two-dimensional sheet structure of graphene, this product forms an ultra-thin coating (less than 1µm thick) with extremely high conductivity on the current collector surface. This significantly reduces interfacial resistance and improves the adhesion of active materials, thereby greatly enhancing battery rate performance and cycle life. Its overall performance surpasses that of coated aluminum foil using ordinary carbon black and graphite modification, and it can replace traditional aluminum foil and etched aluminum foil in widespread applications in lithium-ion batteries and supercapacitors.
