Modified graphene oxide (GO) by a novel alkyne terminated ferrocene (Fc) was successfully synthesized through a click reaction. Afterwards; ternary nanocomposite consisting of modified GO (GO-Fc); Mn3O4; nanoparticles; and polyaniline (PANI) was synthesized via a simple physically mixing procedure for battery-type supercapacitor applications. The structure of the novel alkyne terminated Fc compound was confirmed by proton nuclear magnetic resonance (1H NMR); carbon nuclear magnetic resonance (13C NMR); and Fourier transform infrared spectroscopy (FT-IR). The structure; electrochemical performance; and morphological details of the new materials were investigated with some analyses; including FT-IR; cyclic voltammetry (CV); galvanostatic charge-discharge measurement (GCD); electrochemical impedance spectroscopy (EIS); field emission scanning electron microscopy (FESEM); energy dispersive X-ray (EDX); and X-ray diffraction (XRD) analysis. GO-Fc/Mn3O4/PANI nanocomposite has shown excellent capacity retention (80%) with a high battery-type charge storage capacity of 233 mAh g−1 at 2.5 A g−1. In a two electrode symmetrical system; a high energy density of 42.6 Wh kg−1 along with a high power density of 5.56 kW kg−1 was obtained. Thus; GO-Fc/Mn3O4/PANI nanocomposite can be a very suitable and promising candidate for future energy storage devices. © 2020 Elsevier B.V;
