▎ 摘　　要

NOVELTY - The current collector structure (1) has metal foil substrate (10), and a graphene conductive layer (20) which is provided on at least one surface of the metal foil substrate and comprised of graphene sheets and polymer binder used to bind the graphene sheets together and adhere the graphene sheets to the metal foil substrate. The graphene sheet has a shape of thin flake with thickness of 1 to 50 nanometers and a planar lateral dimension of 1 to 50 micrometers. USE - Current collector structure for e.g. batteries, capacitors. ADVANTAGE - Allows the polymer binder to be well compatible with the binder used in the active material contained in the electrochemical component. Reduces the contact resistance and greatly improves the performance of the electrochemical component since the active material of the electrochemical component is tightly bound with graphene conductive layer. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of the current collector structure. Current collector structure (1) Metal foil substrate (10) Graphene conductive layer (20)
