Correlation Studies between Pore Structure and Electrochemical Performance of Activated Polymer-based Hard Carbon |
| 초록 |
In this study, activated polymer-based hard carbon (APHC) was first prepared using CO2 activation. Then electrochemical measurements of APHC-applied electrodes were used to evaluate these electrodes for application to electric double-layer capacitors. The APHCs were prepared under different conditions of activation temperature and time. APHC-10-40 and APHC-10-50 showed good textural properties (specific surface area: 2440 and 2210 m2/g, mesopore fraction: 43.5 and 63.1%, respectively). These properties were observed using the N2 /77 K adsorption isotherms and APHC have favorable pore structures for ion adsorption in electrolytes. APHC-10-50 showed 117 F/g of specific capacitance in propylene carbonate (PC), but only 106 F/g in acetonitrile (AcN), very different from APHC-10-40 (77 F/g in PC and 120 F/g in AcN). |
