In this work, pre-oxidized petroleum pitch-based activated carbons (ONP-AC) are obtained by the combination of a pre-oxidation at 300°C in oxygen atmosphere and a chemical activation with potassium hydroxide. The effect of pre-oxidation of petroleum pitch as precursor on the electrochemical performances of the ONP-AC was investigated. It was found that micropore volume ratio of ONP-AC was higher than that of the non-oxidized Pitch-baed AC (P-AC). In addition, the electrochemical performance including the current density, charge-discharge, and specific capacitance of the ONP-AC was higher than those of P-AC. The highest specific capacitance (357 F/g) of the electrodes was obtained at a scan rate of 0.2 A/g for the ONP-AC compared to 285 F/g for the P-AC. This result suggested that the improved electrochemical performance of the ONP-AC could be attributed to high micropore volume ratio of ONP-AC, resulting from the active site formed by pre-oxidation.
