▎ 摘　　要

NOVELTY - A current collector comprises resin and carbon material having a graphene laminated structure. In the X-ray diffraction measurement when the carbon material and silicon are mixed in a weight ratio of 1:1, the ratio (a/b) between the height (a) of the highest peak at 2θ of 24-28° and height (b) of highest peak at 2θ of 28-30° , is 0.2-10.0. USE - Current collector used for positive electrode or negative electrode of nonaqueous electrolyte secondary battery (Claimed) for portable devices, hybrid vehicles, electric vehicles, and domestic electric power storage applications. ADVANTAGE - The current collector provides batteries having reduced battery resistance and improved safety.
