We report a facile synthesis and characterization of a less investigated Mixed Transition Metal Oxide (MTMO)- FeCo2 O4 nanostructures on its utilization as electrode material for energy related applications by co-precipitation method. The as-synthesized nanostructures were characterized by thermogravimetery analysis (TG),X-ray diffraction(XRD),Fourier transform infrared spectroscopy(FTIR),Scanning electron microscopy(SEM) and EDAX. Electrochemical properties of the FeCo2 O4 electrode performance were characterized by cyclic voltammetry(CV) and galvanostatic charge-discharge measurements in 1 M KOH electrolyte using a three electrode system. The asymmetric supercapacitor gave a high specific capacitance of 355 F/g at a discharge current density of 10 A/g. Moreover, they showed an excellent cycle stability and better capacity retention of 89% after 2000 continuous charge-discharge cycles. Thus a beneficial attempt have been exerted towards partly displacing the cobalt in somewhat expensive and toxic cobalt based oxide (Co3 O4 ) with cheaper and more environmentally friendly alternate elements without losing its high electrochemical effectiveness.
