Numerous researchers and industries take issue with the safe use of energy storage devices due to electrolyte leakage, overheating, and accidental fire damage. In this aspect, a symmetric capacitor with electrolyte embedded V₂O₅-rGO composite (VGS) is prepared. Electrochemical methods are systematically studied for the prepared composites. The prepared VG20S composite shows an excellent specific capacitance (566.7 mF cm⁻²) with capacity retention of 80.5 % for 3000 cycles. At the same time it showed a maximum power density of 750 W cm⁻² with 15.625 Wh cm⁻² energy density.
