Preparation and application of carbon-coated tin antimony alloy nanofibers

Carbon-coated tin antimony alloy particles were prepared by hydrothermal method using antimony tin oxide nanoparticles( Sn0. 92Sb0. 08O2. 04) as the precursor and glucose as the carbon source,then the electrostatic spinning technique was used to prepare carbon-coated Sn Sb / C nanofibers.Transmission electron microscopy and scanning electron microscopy were used to characterize the morphology of carbon-coated tin antimony nanoparticles and nanofibers,and an X-ray diffractometer was used to assess the structure of nanofibers. The electrochemical properties of carbon-coated Sn Sb / C nanofibers were investigated as a potential high-capacity cathode material for lithium-ion batteries. The results showed that the carbon-coated tin antimony alloy nanofibers were prepared successfully. With the increase of the carbon coated tin antimony alloy content of nanofibers,negative material prepared has the high reversible capacity and good cycle performance.
