Abstract
Metallic Sn-C composites were prepared by using electrospinning and electrostatic spray deposition (ESD). Morphology of the material prepared by these methods can be controlled by changing the experimental conditions such as the flow rate, voltage, composition of precursor solutions. Influence of the morphology on the electrochemical performance for the same composite was studied. Composite fibers prepared by electrospinning and porous films by ESD were characterized using X ray Diffraction, Transmission Electron Microscopy and Electrochemical characterization. Both the fibers and the porous composite films showed good performance compared to the tin nanopowder based anodes. Capacities of 760mAh/g and 686 mAh/g were obtained for Sn@C-hollow carbon nanofibers and Sn-C porous films, respectively.
