研究実績の概要 |
Content: The synthesis of a series of template carbons was achieved by tuning the chemical vapor deposition time period. The carbon structures were characterized by X-ray diffraction, thermogravimetry, nitrogen adsorption-desorption, Raman spectroscopy, and temperature-programmed desorption. The preliminary electrochemical performance was evaluated by using cyclic voltammetry in a three-electrode cell.
Importance: Template carbons with controllable pore size, graphene stacking number, and edge sites were successfully synthesized. Especially the number of edge sites was quantified. According to the electrochemical performance, carbons with fewer edge sites show improved stability in the ionic liquid-based supercapacitors. Based on this result, a new record of high working voltage is promising.

今後の研究の推進方策 |
1. Test the performance of templated carbons in ionic liquid-based supercapacitors in a two-electrode testing cell. The cyclic voltammetry, long-term charge/discharge, and electrochemical impedance will be tested. 2. Confirm the highest working voltage that the templated carbons can achieve. 3. Compare four different types of ionic liquids.
