摘要
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, Fe2O3 and Fe3O4/C composites were obtained from Fe-based MOFs through thermal treatment. Both Fe2O3 and Fe3O4/C composites demonstrated high capacity and excellent cycling stability.
