Abstract

The objective of this work was to improve the capacitive behavior of rGO-CNTs composite electrode. The prepared composite has been examined for electric double layer capacitor (EDLCs) devices. The structural and chemical properties of the composite has been validated by X-ray diffraction (XRD), Raman spectroscopy and scanning electron microscope (SEM). We performed the cyclic voltammetry (CV) and measured specific capacitance of 54 Fg⁻¹at 10 mV/s for 1 M H₂SO₄ and 36.25 F g⁻¹ for 1 M KOH liquid electrolyte. From galvanostatic charge-discharge (GCD) studies, 1 M H₂SO₄ electrolytes we obtained the energy density and power density as 10.67 Wh kg⁻¹ and 2400 W kg⁻¹ respectively at 6 A/g. However, 1 M KOH electrolytes has an energy density and power density of 1.7 Wh kg⁻¹ and 1600 W kg⁻¹ at 4 A/g. Therefore, the performance of 1 M H₂SO₄ electrolytes shows better results as compared to the 1 M KOH. Hence, we conclude that rGO-CNTs electrode is an interesting material for supercapacitor applications.
