• Effect of electrolyte concentration on the electrochemical performance of RGO–KOH supercapacitor

The electrolyte used, plays a crucial role in the electrochemical performance of supercapacitors. It is known that the concentration of electrolyte is also a controlling parameter for a given active material where the performance will be optimum for a particular concentration. Herein, we report a study on the effect of electrolyte concentration on the electrochemical performance of reduced graphite oxide–potassium hydroxide supercapacitor. The supercapacitor achievesa maximum specific capacitance of 232 F g$^{-1}$ in 6 M KOH with energy and power density values of ${\sim}$21 Wh kg$^{-1}$ and ${\sim}$400 W kg$^{-1}$, respectively. The kinetics of charge storage reveals that the combination of surface phenomenon andintercalation process leads to maximum specific capacitance.
