<P>FeF<SUB>3</SUB> is of great interest as a potential candidate cathode material because of its low cost, abundance, environmental friendliness, and high theoretical capacity of about 237 mAh·g<SUP>–1</SUP> ...
<P>FeF<SUB>3</SUB> is of great interest as a potential candidate cathode material because of its low cost, abundance, environmental friendliness, and high theoretical capacity of about 237 mAh·g<SUP>–1</SUP> in the voltage range of 2.0–4.5 V. However, FeF<SUB>3</SUB> has drawbacks of poor cycling stability and rate performance because of its low intrinsic electrical conductivity and slow diffusion of lithium ions. These issues should be improved for the practical application of FeF<SUB>3</SUB> in lithium-ion battery systems. In this study, FeF<SUB>3</SUB>/ordered mesoporous carbon (OMC) nanocomposites were synthesized by an incipient-wetness impregnation technique in a facile and scalable method. The tubular shaped OMC was utilized as both a conductive agent and a hard template for the formation of nanosized FeF<SUB>3</SUB> particles. The FeF<SUB>3</SUB>/OMC nanocomposites showed enhanced capacity, cycling stability, and rate performance compared to bulk FeF<SUB>3</SUB> in the voltage range of 2.0–4.5 V at room temperature.</P><P><B>Graphic Abstract</B>
