In this work, electric double layer capacitor of electrode which are composed of activated carbons, and 1 M ET4NBF4/PC as electrolyte, were prepared. The effect of acidic treatment on activated carbon of the capacitor was studied in charge-discharge capacitance, self discharge voltage, and impedance properties. The capacitance of the charge-discharge was evaluated using MACCOR tester. The impedance properties were measured by PARSTAT impedance tester. In this work, the modification of carbons led to improve of capacitance or impedance properties, resulting in increasing the interfacial or dispersion properties of the adsorbent solids studied. |
