Abstract:
Herein, we report the impregnation of chloranil into activated carbon micropores using scCO2. The sample prepared under 105 °C and 15 MPa showed a specific capacity of 81 mAh gelectrode-1, except for the electric double layer capacity at 1 A gelectrode-Polytetrafluoroethylene (PTFE)-1. Additionally, approximately 90% of the capacity was retained even at 4 A gelectrode-PTFE-1.
