V2O5 nanowires were doped with Ru4+ using a hydrothermal process. RuxV2−xO5 composites were characterized by x-ray diffraction, energy-dispersive x-ray analysis, scanning electron microscopy (SEM) and high-resolution transmission electron microscopy (HRTEM). The electrochemical performance of the RuxV2−xO5 nanowires/carbon composites were evaluated by cyclic voltammetry and galvanostatic charge-discharge techniques. The RuxV2−xO5/carbon exhibited a maximum specific capacitance of 351 F·g−1 at a scan rate of 5 mV/s in a symmetric coin cell device. The asymmetric hybrid supercapacitor device achieved a specific cell capacitance of 237 F·g−1 at a scan rate of 5 mV/s, which delivers a high energy and power of 74.8 Wh·kg−1 and 5994.5 W·kg−1, respectively. |
