In this study, the activated carbon (AC) was modified via boric acid treatment to improve capacitance. After boric acid treatment, functional groups ratio of Quinone-like (O=C) which is electrochemical active functional group was increased. And, Boric acid treated AC showed an increase in the specific surface area, total pore volume and micropore volume. In case of optimum condition of boric acid treatment on AC, its specific capacitance increased by 20% in comparison to that of untreated AC. These results demonstrate that a boric acid treated carbon surface-based electric double layer capacitor electrode effectively enhances specific capacitance. |
