Influence of Mesoporous Structure on Electrochemical Performance for EDLCs of Ordered Mesoporous Carbon Materials (CMK-3 and CMK-8) |
| 초록 |
We fabricated ordered mesoporous carbon materials (OMCs, CMK-3 and CMK-8) via a nano-casting method using mesoporous silica as the template materials and furfuryl alcohol (FA) as a carbon source. The OMCs showed a higher specific capacitance than the microporous carbon samples obtained by the carbonization of FA without templates. The enhancement of the specific capacitance may come from the mesopores of OMCs. The large pores and high specific surface area of OMCs are beneficial for the fast electrolyte transportation and high ion storage capability during the charge-discharge process. Moreover, CMK-3 (prepared using SBA-15) exhibited better EDLC performance than CMK-8 (prepared using KIT-6). CMK-3 possessed the long straight channels, which facilitate lower internal resistance and a larger number of ion-transport pathways than CMK-8 with the Ia3d cubic channels. The EDLC performance of carbon-based materials strongly depends on the mesopore structure and the mesoporous surface area. |
