▎ 摘 要
NOVELTY - The collector has a collector main body whose surface is provided with a vertical orientation graphene nano sheet. Height and thickness of the graphene nano sheet are respectively 50 nm to 5 microns and 10 nm. The collector main body is made of copper, aluminum foil, stainless steel, cast iron and nickel sheet materials. USE - Current collector for an energy storage device e.g. super capacitor and secondary battery. ADVANTAGE - The collector can contact with an active material to reduce internal resistance. The collector has high power density. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a current collector manufacturing method. DESCRIPTION OF DRAWING(S) - The drawing shows a photographic view of a current collector.
