▎ 摘　　要

NOVELTY - A current collector comprises a collector foil on at least one surface containing a graphene and a binder coating. USE - Current collector is used for battery. ADVANTAGE - The current collector has excellent adhesiveness with respect to active material. The battery comprising the current collector has reduced internal resistance, and excellent charging and discharging characteristics. The contact area between graphene and current collector is large. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of current collector, which involves dispersing graphene and binder in solvent to form slurry, coating the slurry on the current collector foil on at least one surface, and drying.
