摘要：
Our work demonstrates Cu current collector modified by graphene film grown by chemical vapor deposition to enhance contact resistance and adhesion with graphite anode electrode. The graphene film turned Cu surface more hydrophobic and improved its adhesion with graphite anode layer. In addition, the electrochemical characterization results showed that the introduction of graphene film not only increased discharge capacity, but also significantly improved cycle stability of the graphite anode electrode. This enhancement in electrochemical performances can be associated to the reduction of charge transfer resistance of the cells by the introduction of graphene on Cu current collector.
