Synthesis and Electrochemical Performance of Carbon-coated FeF2 Nanocomposite†

doi:10.7503/cjcu20190169

Abstract

Abstract:

A hybrid nanostructure of FeF₂ coated by carbon was synthesized through thermal decomposition at high temperature, and its structure and morphology were characterized. The results show that FeF₂ is successfully coated by carbon, and Fe₃C is partially formed. The electrochemical measurements show the obtained material displays a reversible discharge capacity of 246.7 mA·h/g after 100 cycles at 0.1C, and the capacity retention is up to 93.6% compared with the discharge capacity at the second cycle, exhibiting excellent cycling stability.

Key words: FeF₂, Carbon coating, Cathode material, Lithium-ion battery
