Functional nanomaterials with three-dimensional hierarchical structures are of high interest for many practical applications including lithium-ion batteries (LIBs). In this work, self-organized sheaf-like Fe3O4/C microrods constructed by porous nanowires have been synthesized by a facile solvothermal method combined with a subsequent annealing treatment. The morphology of the building blocks could be easily tuned by varying the synthesis parameters. When applied as an anode material for LIBs, these sheaf-like Fe3O4/C porous microrods manifest superior electrochemical lithium storage properties in terms of high reversible capacity, stable cycling capacity retention and good rate capability.
具有三维层次结构的功能纳米材料在包括锂离子电池（LIBs）在内的许多实际应用中备受关注。在这项工作中，通过简便的溶剂热法结合后续退火处理，合成了由多孔纳米线构建的自组装束状Fe3O4/C微棒。通过改变合成参数，可以轻松调节构建块的形态。当用作LIBs的负极材料时，这些束状Fe3O4/C多孔微棒在高可逆容量、稳定的循环容量保持率和良好的倍率性能方面表现出优异的电化学锂存储性能。
