dc.description.abstractHybrid nanocomposites provided a synergistic improvement on electrochemical performance and stability for pseudocapacitor. Designed graphene/carbon nanotubes (CNTs)/MnO2 nanocomposites with CNTs electrode (in short, GMC + C) with highly nanoporous framework surface structure are fabricated by a modified electrophoretic deposition (EPD) method. Scanning electron microscopy and transmission electron microscopy analysis demonstrate that the flake-like MnO2 thickness (about less than 10 nm) and uniformly distributed on the porous graphene/CNTs framework. X-ray diffraction shows the formation of birnessite-type MnO2. Pseudocapacitances of the GMC + C electrode calculated by cyclic voltammetry having different scan rates of 5, 20, 50, 100, and 300 mV s(-1) exhibit high specific capacitances of 481, 436, 413, 398, and 372 F g, respectively. Sodium ion diffusion coefficients of the GMC + C electrode show a higher intercalation value of 3.647 x 10(-8) cm(2) s(-1) and deintercalation value of 2.899 x 10(-8) cm(2) s(-1) using chronoamperometry. Moreover, the GMC + C electrode maintains a high specific capacitance of 346 F g(-1), and is about 833% of the initial capacitance after 15,000 charge/discharge cycles. The designed hybrid GMC + C nanocomposites pseudocapacitor electrode using EPD route with the high specific capacitance, fast reaction rate, and high stability, exhibits high potential for practical applications.
