Abstract

Graphene-wrapped FeF3 nanocrystals (FeF3/G) have been successfully fabricated for the first time by a vapour-solid method, which can be generalized to synthesize other metal fluorides. The as-synthesized FeF 3/G delivers a charge capacity of 155, 113, and 73 mA h g -1 at 104, 502, and 1040 mA g-1 in turn, displaying superior rate capability to bare FeF3. Moreover, it exhibits stable cyclability over 100 cycles with a charge capacity of 185.6 and 119.8 mA h g-1 at 20.8 and 208 mA g-1, respectively, which could be ascribed to the buffering effect and lowered resistance from the graphene. This versatile vapour-solid method and the improved cyclability provide a promising avenue for the application of metal fluorides as cathode materials. © 2013 The Royal Society of Chemistry.
