The surface modification on electrode materials generally improves the electron mobility and surface interactions at carbon materials. Exfoliate graphite has been prepared by the ball milling technique with three different milling time. The graphene oxide, reduced graphene oxide were prepared modified Hummers method and carbon quantum dots was prepared using chemical synthesis-pyrolysis technique. The synthesized materials were characterized by X-ray diffraction (XRD), Transmission electron microscopy (TEM), and investigated the electrochemical performances of Cyclic Voltammetry (CV) analysis to understand their specific capacitance.
