Fluorographene exfoliated by the intercalation of organic molecules for lithium primary batteries

摘要

Fluorographene (FG) is considered as one of important candidate materials for advanced technological applications because of its distinctive electrical and electronic properties. Recently, a solvothermal-assisted exfoliation shows a great potential for the preparation of high-quality single-or few-layer nanomaterials. High temperature and pressure reduce the free energy, weaken van der Waals attraction between adjacent layers and promote the intercalation of solvent molecules into interlayers. In this work, FG was prepared by the solvothermal exfoliation of F-graphite through the intercalation of organic solvents. FG showed wrinkled few-layered microstructures and the poor regularity along the stacking direction. The electrochemical performance of FG nanosheets was tested as the cathode material of Li-battery at different current densities.
