The use of a Fe-based metal organic framework(MOF), namely MIL-88B(Fe), as active material for lithium ion batteries(LIBs) is reported for the first time in the present work. Fe-based MOF demonstrated high capacity, excellent cycling stability and rate performance when used as anode. A highly reversible capacity of 680 mAhg~(-1) after 500 cycles at a current density of 200 m A g~(-1) was obtained. In addition, Fe_2O_3 and Fe_3O_4/C composites were obtained from Fe-based MOFs through thermal treatment. Both Fe_2O_3 and Fe_3O_4/C composites demonstrated high capacity and excellent cycling stability.
