在这项工作中，第一次，我们通过煅烧锡金属有机框架（MOF）前体合成SnO 2纳米材料。X射线衍射，场发射扫描电子显微镜，透射电子显微镜，和Brunauer-Emmett-Teller比表面积被用来表征相和观察表面形貌。该负极材料在LIB中表现出良好的电化学性能，具有高可逆容量和循环稳定性。良好的电化学性能可以归因于电子和锂离子的短传输/扩散路径以及由纳米结构的SnO 2导致的电极和电解质之间的高接触面积。这是低成本，方便和可扩展的大规模生产的SnO 2纳米复合材料作为下一代锂离子电池的潜在阳极材料。
In this work, for the first time, we synthesize a SnO2 nanomaterial through the calcination of tin metal–organic framework (MOF) precursors. X-ray diffraction, field emission scanning electron microscope, transmission electron microscopy, and the Brunauer–Emmett–Teller specific surface area are used to characterize the phases and to observe surface morphologies. This anode material exhibits good electrochemical performance in LIBs with high reversible capacity and cycling stability. The good electrochemical properties could be ascribed to the short transport/diffusion path of electrons and lithium ions and the high contact area between the electrode and electrolyte that results from the nanostructured SnO2. This is low-cost, facile and scalable for mass production of SnO2 nanocomposites as a potential anode material for the next-generation LIBs.
