Porous Fe2O3/ZnO composite derived from MOFs as an anode material for lithium ion batteries

With the ability of large specific capacities and long cycle life, hybrid materials containing iron oxides are extensively investigated as anode materials for lithium-ion batteries (LIBs). In this work, Fe2O3/ZnO mesoporous bi-components were prepared by using solvothermal MOFs templating method and then an annealing process. When used as an anode material for lithium-ion batteries, thus-obtained composite showed excellent electrochemical performance, including good charge and discharge specific capacity, excellent rate capacity and a relatively stable cycle performance (ca. 700 mA h g−1 at a current density of 100 mA g−1 after 60 cycles). This novel method for the synthesis of functional hybrid materials can be open up the preparation of various MOFs-derived functional nanocomposites in lithium-ion batteries.
