 note = {In this study, a high-capacity electric double layer capacitor (EDLC) and elucidation of degradation mechanism of EDLC were targeted. Firstly, powdery activated carbons were treated using dielectric barrier discharge in which operation gas was mixed gas of Ar and O2 for increasing surface area. As the results, surface area of 15 s-treated-activated-carbon increased in comparison with parent ones. Also, capacitance of EDLC using the 15 s-treated-activated-carbons increased in comparison with parent ones. Therefore, it was clearly understand that oxygen plasma treatment of powdery activated carbon was effective, and the most suitable time of plasma treatment of activated carbon for EDLC was 15 s. Secondly, the accelerated aging test of EDLC was taken for finding deterioration factor. As the results, the capacitance decreased and the internal resistance increased when charging voltage was high. In addition, moisture content of the deteriorated sample increased. Therefore, it was clearly understood that charging voltage and moisture content of electrolyte were one of the deterioration factor.},
