Graphene (Gr) synthesized by electrochemical exfoliation method has been used to prepare the composite material (PbO2-Gr) including different amounts of graphene (1 and 5%). Taking into account the advantages of the high conductivity of Gr and the capacitance of PbO2, as a reference, the PbO2-Gr composite material served for the application in lead-acid batteries as a positive electrode. On one hand, the morphology and structure of the whole pure graphene, PbO2, and PbO2-Gr were characterized by different technics XRD, TEM, and electrical conductivity. The electrochemical performance was evaluated by electrochemical impedance spectroscopy (EIS), cyclic voltammetry, and galvanostatic discharge tests. The discharge capacity of the PbO2 material experienced is around 40mAh which witnessed an increase of 53mAh regarding the composite material PbO2-Gr1%.
