In the present work, binder-free MnCo2O4 nanoflakes were prepared using a cost-effective potentiostatic mode of electrodeposition. Structural and microstructural features of the prepared MnCo2O4 samples were examined by different characterization techniques including X-ray diffraction, Raman, field emission scanning electron microscopy, energy-dispersive X-ray spectroscopy and supercapacitive testing. The morphological investigation revealed that a unique nanoflake-like structure with uniform morphology. The electrochemical properties of MnCo2O4 nanoflakes were investigated by cyclic voltammetry, galvanostatic charge discharge and electrochemical impedance spectroscopy. The maximum specific capacitance observed for the MnCo2O4 thin films was 585 F g−1 for a current density of 0.2 mA cm−2. Our results indicate that the MnCo2O4 electrode has potential for application in supercapacitors.
