Increasing the energy density and power of supercapacitors through hybrids carbonaceous materials metal oxides continues to be subject numerous research works. The correlation between specific capacitance properties used as electrodes attracts great interest. In present study, we have investigated composites (GO/Mn3O4) prepared by hydrothermal method with variable ratio GO/Mn3O4 tested supercapacitor electrode in three two-electrode cells. chemical characterization carried out X-ray Photoelectron Spectroscopy adsorption techniques allowed determination surface carbon oxygen content, well its textural properties. this work analyzed contribution double layer Faradaic reactions value final supercapacitance synthesized materials. Beyond empirically obtaining electrochemical properties, these been related physicochemical characteristics hybrids, help design best performances for electrodes.
