MnO2-CB made by the in situ direct coating method to deposit MnO2 onto CB; then PANI coating was coated on it. Morphology of the nanocomposite was studied by X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy and scanning electron microscopy (SEM). The electrochemical properties of electrodes were investigated by cyclic voltammetry (CV), galvanostatic charge–discharge and electrochemical impedance spectroscopy (EIS) techniques in 0.5 M Na2SO4. The specific capacitance of 179.8 F. g-1 was obtained for PANI/MnO2-CB compared with 121 F. g-1 for MnO2-CB and 44.87 F. g-1 for CB. The EIS results also revealed improved capacitive properties of CB by the addition of MnO2 and PANI. %U https://www.ijnnonline.net/article_14568_59d8ebdd04dd8262f552a177fcb77ddd.pdf
