摘要：Fabrication of porous micro/nanostructures with high electronic conductivity is very efficient for enhancing the electrochemical performance of transition metal oxide-based anode materials for lithium-ion batteries. Here, we successfully propose Zn2SnO4 composites functionalized using biomass-derived carbon and metal-organic framework derived MnO/C. The fabricated LC@Zn2SnO4@MnO/C composite exhibits superior electrochemical performance with a reversible capacity of 1185.6 mA h g(-1) at 200 mA g(-1) and maintains 552 mA h g(-1) even at 2 A g(-1) for 150 cycles. The significantly improved performance suggests that the unique structure constructed by MOF-derived oxide decoration and dual-carbon coating can efficiently enhance the material integrity and facilitate charge transfer upon repeated (de)lithiation processes, demonstrating a general strategy for the preparation of mixed-metal-oxide nanostructures for batteries with improved electrochemical performance.
