A study on pore development of activated hard carbon for supercapacitors |
| 초록 |
In this work, activated hard carbons (ACs) were prepared from polymeric precursors by physical activation with CO2 for the electrode materials of supercapacitors. Textural properties were studied by Brunauer-Emmett-Teller equation with N2/77K adsorption isotherms. And the structural characteristics and surface morphologies of the ACs were observed by X-ray diffraction (XRD) and scanning electron microscopy (SEM), respectively. The electrochemical behaviors were studied by galvanostatic charge–discharge, cyclic voltammetry (CV), and electrochemical impedance spectroscopy (EIS) test, respectively. The ACs were applied as an electrode for EDLCs and analyzed in relation to the activation conditions. |
