Abstract

In the present work, binder-free MnCo ₂ O ₄ nanoflakes were prepared using a cost-effective potentiostatic mode of electrodeposition. Structural and microstructural features of the prepared MnCo ₂ O ₄ 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 MnCo ₂ O ₄ nanoflakes were investigated by cyclic voltammetry, galvanostatic charge discharge and electrochemical impedance spectroscopy. The maximum specific capacitance observed for the MnCo ₂ O ₄ thin films was 585 F g ⁻¹ for a current density of 0.2 mA cm ⁻² . Our results indicate that the MnCo ₂ O ₄ electrode has potential for application in supercapacitors.
