Abstract
• A facile green strategy is developed to synthesize the MnO-based anode materials. • MOF derived carbon matrix and graphene greatly enhance the conductivity. • The MnO@rGO shows high reversible capacity and superior electrochemical stability. Although metal-organic frameworks (MOFs) derived MnO-based materials exhibit high reversible capacity over commercial anode materials, their practical application is still impeded due to the drawbacks of conventional synthetic methods, such as environmental hazards and economic costs. Herein, we report a facile and eco-friendly water-based route for the in-suit synthesis of Mn-MOF precursors, which are applied to prepare MnO and MnO@rGO anode materials through one-step pyrolysis. When fabricated as anode for Lithium-ion batteries (LIBs), MnO@rGO composite achieves superior electrochemical performance in comparison to pristine MnO. Exceedingly, it retains high reversible capacity of 920 mAh g −1 even at 2000 mA g −1 after 160 cycles, which is around 1.8 times of pristine MnO.
