摘要	This paper reports a FeF3 center dot 0.33H(2)O/multi-walled carbon nanotubes (MWCNTs) composite for energy storage applications. The composite material is prepared by solvothermal reaction with FeF3 center dot 3H(2)O and MWCNTs as precursors, and FeF3 center dot 3H(2)O was removed of crystalliferous water and converted to FeF3 center dot 0.33H(2)O during solvothermal treatment. Structural characterizations show that FeF3 center dot 0.33H(2)O that crystalline with a diameter of about 30 nm were distributed in the network of MWCNTs. As a cathode material for lithium ion batteries, FeF3 center dot 0.33H(2)O/MWCNTs was superior to pure FeF3 center dot 0.33H(2)O in terms of high capacity (an initial capacity of 181 mAh g(-1) in 2.0-4.3 V at 20 mA g(-1)), good cycleability (50% capacity retension at 50th cycle) and good rate capability (116 mAh g(-1) at 100 mA g(-1)). The enhanced performances were attributed to the conductive MWCNT network which improved the electron transport ability and buffered volume change of the cathode.
