Facile synthesis of C-FeF₂ nanocomposites from CFx: influence of carbon precursor on reversible lithium storage.

ABSTRACT: Transition metal fluorides are an important class of cathode materials for lithium batteries owing to their high specific energy and safety. However, metal fluorides are electrical insulators, exhibiting slow reaction kinetics with Li. Consequently, metal fluorides can show poor electrochemical performance. Instead, carbon-metal fluoride nanocomposites (CMNFCs) were suggested to enhance electrochemical activity. Chemical synthesis of CMNFCs poses particular challenges due to the poor chemical stability of metal fluorides. Recently, we reported a facile one-step method to synthesize carbon-FeF₂ nanocomposites by reacting fluorinated carbon (CFx) with iron pentacarbonyl (Fe(CO)₅) at 250 °C. The method resulted in C-FeF₂ nanocomposites with improved electroche
