Journal Article 2014 06 26 <em>The supercapacitive behavior of polyaniline/MnO₂-carbon black (PANI/MnO₂-CB), MnO₂-CB nanocompositesand CB was studied. MnO₂-CB made by the in situ direct coating method to deposit MnO₂ onto CB; then PANI coating was coated on it</em><em>. Morphology of the nanocomposite was studied by </em><em>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.</em> https://www.ijnnonline.net/article_14568_77004ef63f2ef7dab481a16152f60c43.pdf
