Abstract:

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 mA h g-1 after 500 cycles at a current density of 200 mA 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.
