Abstract

Herein, we synthesized a novel composite electrode material by incorporating vanadium pentoxide nanobelts (VONB) in plasma spray exfoliated graphene (PSEG) using facile ultrasonication technique. Electrochemical behaviour of the synthesized composite was studied using cyclic voltammetry (CV), galvanostatic charge/discharge (GCD) and EIS. A symmetrical supercapacitor was fabricated using 3 wt% V₂O₅ in PSEG (VG3) within a large potential window of −1V to 1 V in 1 M Na₂SO₄ electrolyte. VG3 demonstrated an energy and power density of 46.5 Wh/kg and 2000 W/kg respectively with cyclic stability of 96.50 % up to 10,000 cycles.
