Abstract
Although FeF3 and its hydrates have been studied as the cathode materials for Li ion batteries (LIBs), herein the FeF3/graphene composite with sheet-like structure is innovatively prepared and used as LIB cathode material. By scanning electron microscope (SEM), transmission electron microscopy (TEM), high-resolution TEM (HRTEM), X-ray diffraction (XRD) and electrochemical measurement, the structure and electrochemical performance of the as-synthesized FeF3/graphene composite are investigated. The results indicate that the sheet-like structure hybrid is formed by the FeF3 nanosheets and the graphene sheets. Meantime, we demonstrate that the FeF3/graphene composite has good rate capability and cycling performance, whether it is based on conventional intercalation reaction or reversible conversion reactions.
