Novel and scalable solid-state synthesis of a nanocrystalline FeF3/C composite and its excellent electrochemical performance

Abstract

A scalable solid-state reaction is presented to synthesize an FeF₃ cathode material by using PTFE as a source of both fluorine and carbon. The method yields nanocrystalline FeF₃/C showing excellent electrochemical performance even without any conducting additive. This method can be utilized for engineering MFs’ properties and developing other fluorine compounds.
