A scalable formation of nano-SnO2 anode derived from tin metal-organic frameworks for lithium-ion battery

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...

Summary: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.
