The need for growth in the development of energy supply devices such as batteries and large capacitors has led to the improvement and innovation of these devices so that they store energy efficiently, and additionally they must be small, light, with low production costs, and friendly to the environment. For these reasons, in this investigation results of the development of graphene-based electrodes to be used in batteries are presented. The graphene was synthesized by means of the electrochemical exfoliation technique and deposited as a coating on common glass via the spray technique, and over this coating an Mn2O3 coating was deposited by means of spin coating. The study and characterization of the chemical properties was carried out using the Raman spectroscopy and X-ray photoelectron spectroscopy techniques. In addition, the electrochemical properties of the electrodes were evaluated by means of potentiostat measurements. The Raman results showed the presence of peaks D and G, located at 1534 and 1597 cm-1, respectively. The electrochemical measurements indicated that the density current in the discharge process of the Mn2O3-Cu electrode system was improved by approximately 3 times with the Graphene-Mn2O3-Cu electrode system.
