Abstract:
FeF[Formula: see text]H 2 O/C composite is prepared by using ferric citrate (FeC 6 H 5 O[Formula: see text] as precursor via carbonization and fluoridation. When evaluated as cathode materials for lithium batteries, the as-prepared FeF[Formula: see text] H 2 O/C composite can retain a capacity of 116[Formula: see text]mAh[Formula: see text] g[Formula: see text] at 40[Formula: see text] mA[Formula: see text]g[Formula: see text] after 300 cycles in the voltage range of 2.0–4.5 V. The cycling performance should be attributed to Fe 2 F[Formula: see text]H 2 O as a main component and carbon decoration. The electrical conductivity of Fe 2 F[Formula: see text]H 2 O is higher than other iron fluorides, and it also possesses an open framework in its crystal structure for facilitating the transport of Li[Formula: see text]. The simple preparation, unique crystal structure and superior electrochemical performance of FeF[Formula: see text] H 2 O/C composite show its great potential of being an alternative cathode material for lithium batteries.
