Hierarchical mesoporous structured iron based fluorides (abbreviated as HMIFs) are successfully synthesized for the first time by a solvothermal method through self-assembly. The fluorides are built from a large amount of nanorods with a size more than a dozen nanometers and exhibit dual phases consisting of Fe1.9F4.75 center dot 0.95H(2)O and FeF3 center dot H2O. A possible formation mechanism is proposed by systematically investigating the synthesis conditions including temperature, reaction time and the amount of the fluorides source. The electrochemical performance of HMIFs as cathodes for rechargeable lithium batteries is investigated. A large reversible capacity exceeding 200 mA h g(-1) without any conducting agent coating and excellent cyclic performance with a residual capacity of 148 mA h g(-1) after 100 cycles are obtained at 0.1 C. In addition, an outstanding rate performance exceeding 100 mA h g(-1) at 5 C highlights the advantages of HMIFs materials for energy storage applications in high-performance LIBs.
