Electrochemical property of phenol-based activated carbon derived from SiO2 on electric double layer capacitor electrodes |
| 초록 |
Electrochemical performance of electric double layer capacitor is depending on the specific surface area and pore structure of the activated carbon (AC) electrode material. Therefore, the controlled pore structure of AC is crucial for the improvement of EDLC capacity. To improve the EDLC capacity, phenol-based activated carbon materials with dual pore structure manufactured. The Phenol-based carbon material with high surface area and facilitate pore development prepared from SiO2 template and KOH activation for mesopore and micropore respectively. The textural properties of them were assessed BET, and DFT methods. And the electrochemical properties of them were evaluated using cyclic voltammetry. There was no correlation between the specific surface area and the template contents. But mesopore volume was increased with increasing SiO2 quantity. Specific capacitance was the highest on topmost specific surface area and mesopore structure. |
