Synthesis and characterization of in situ Fe2O3-coated FeF3 cathode materials for rechargeable lithium batteries
Abstract
Here, a novel architecture of a core–shell structured FeF3@Fe2O3 composite with particle size of 100–150 nm and tunable Fe2O3 content is synthesized by a simple heat treatment process utilizing FeF3 with fine network structure as precursor. The structure, morphology and electrochemical performance of the pristine FeF3 and the FeF3@Fe2O3 composites are studied by
