▎ 摘　　要

NOVELTY - Current collector (12) comprises a metal foil (122) comprising at least one surface, and a graphene film (124) coated on the surface of the metal foil. USE - The current collector is useful in an electrode of an electrochemical battery (claimed). ADVANTAGE - The current collector exhibits: small contact resistance with electrode active material disposed on it, and thus improves the performance of the electrochemical battery; and increased conductivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for an electrode (10) of an electrochemical battery comprising the current collector, and at least one electrode active material layer (14) coated on at least one surface of the current collector, where the graphene film electrically contacts the electrode active material layer. DESCRIPTION OF DRAWING(S) - The figure shows a schematic structural view of the electrode of the electrochemical battery.
