Enhanced electrochemical performances of nanocarbon composite based supercapacitor with ion-gel electrolyte. |
초록 |
The reduced graphene oxide (rGO)/activated carbon (AC) composites are coated on the aluminum substrate using spray coating technique to fabricate nanocarbon based supercapacitor. Polymer based solid-state xanthan-gum/Na2SO4 electrolyte is also introduced to increase stability of the supercapacitor. The electrochemical properties of the supercapacitor are evaluated by using cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS) and galvanostatic charge/discharge tests. The highest capacitance value of the rGO/AC composite based supercapacitor is 120 F/g. The rGO/AC composite based supercapacitor is also retained ~85% of its initial capacitance value after application of the 3000 galvanostatic charge/discharge cycles. |
