In this regard, MnCo2O4 is synthesized and subsequently hybridized with reduced graphene oxide (rGO). The structure and morphology of the as-prepared materials are confirmed by X-ray diffraction spectroscopy, Raman spectroscopy, and microscopy techniques. The electrochemical analysis is performed by cyclic voltammetry, electrochemical impedance spectroscopy, and galvanostatic charge-discharge techniques. The results show that the addition of rGO to the MnCo2O4 has a good effect on specific capacitance, stability, and increasing the discharge time of the prepared electrode. MnCo2O4/rGO hybrid indicates a specific capacity of 702 F/g and significant stability of 94% during 5000 cycles. Thus, this material can be considered a very promising candidate for usage in the superconducting electrodes.
