▎ 摘　　要

A graphite-mediated microwave-based strategy was used for solid-state exfoliation of graphite fluoride in a few seconds, followed by a simple yet efficient separation to obtain exfoliated materials based on the density difference between graphite and graphene fluoride in solvent. The microwave-exfoliated graphene fluoride was a few layers thick and electrically conductive. The electrochemical testing of pouch-cell supercapacitors assembled by using the exfoliated graphene fluoride electrodes and a novel microemulsion-based electrolyte showed reasonable performance with typical electrical double-layer capacitance behavior and good rate capability (gravimetric specific capacitance: 3.2 F g(-1) at 500 mA g(-1) and 3.1 F g(-1) at 5000 mA g(-1)). The BET specific surface areas of the as-exfoliated graphene fluoride are similar to 60-80 m(2) g(-1), which could be increased by activation using this simple yet versatile microwave-based method for further improvements on the electrochemical performance.
