| Popis: | Carbide-derived carbon (CDC) is an attractive electrode material for electrochemical applications because diverse pore textures and structures can be controlled by changing the properties of the precursor template and the synthesis conditions. Upon the tailoring of the micro-pore texture and graphitic structure of CDCs via a pre-vacuum treatment of a carbide precursor, the electrode shows a greatly high increased capacitance under a range of scan rates from 2 mV/s to 10 mV/s. The specific capacitance of a CDC chlorinated at 1000 °C from a pre-vacuum-treated at 1700 °C was 150 F/g at 2 mV/s, which is approximately 60% higher than that of a CDC chlorinated at 1000 °C. |
