Abstract: α-MnO₂ nanowires with smooth surface, good dispersibility and large aspect ratio were synthe-sized by a hydrothermal method. Then, α-MnO₂ nanowires were mixed with NH₂-RGO and MWCNT ata certain mass ratio, and vacuum-filtrated to obtain α-MnO₂NW_S/NRGO/MWCNT composite film elec-trode material with high areal specific capacitance and good flexibility. The morphology and composition were characterized by scanning electron microscope(SEM) and energy dispersive spectrometer(EDS), and phase structure and valence states were analyzed by X-ray diffraction(XRD) and X-ray photoelec-tron spectroscopy(XPS). The electrochemical test results show that the area specific capacitance of α-MnO₂NW_S/NRGO/MWCNT-8 film electrode delivers an areal specific capacitance of 495.7 mF ·cm^-2 at the current density of 1 mA ·cm^-2, while the current density was increased to 10 mA ·cm^-2, the spe-cific capacitance maintains at 342.0 mF ·cm^-2. The tensile strength of film electrode is 2.41 MPa withelongation of 1.32 %. α-MnO₂ nanowires could fully realize its pseudocapacitance of MnO₂ due to theirshort diffusion path and large active area. NRGO and MWCNT increase the conductivity of film elec-trode, and meanwhile one-dimensional nanowires and nanotubes could help to prevent stacking of gra-phene nanosheets. Such film electrode shows application potential for flexible and light ultracapacitors.
