EDLC characteristics in the Pore size of Activated Carbon |
| 초록 |
The effect of pore size on response characteristic of an electric double layer capacitor (EDLC) was closely examined. A series of phenol-resin-based activated carbon (AC) samples was prepared as average pore size (0.94~1.68) by KOH activation. The impedance properties of pouch-type EDLC cells prepared using AC samples were evaluated by applying an alternating current at 3 V between 10 mHz and 100 kHz. The cell based on the AC with a largest pore size (1.68 nm) showed fast response frequency, and had a high dielectric relaxation time constant. The AC with the largest pore size was confirmed to facilitate extremely low electrolyte-diffusion resistance during the formation of the electric double layer. The presented findings suggest that AC with a largest pore size as the electrode leads to superior capacitance and response frequency characteristics in the alternating current. |
