Abstract：A large Sn/C non- woven film with high capacity and good cycleability have been prepared by an electrospinning of a mixture solution of SnCl4 and PAN, followed by heat- treatment at high temperature. Scanning electron microscopy (SEM), and X- ray diffraction (XRD) analyses demonstrated the morphology and the structure of the Sn/C nanofibers. At first cycle, the Sn/C nanofiber delivers high charge and discharge capacities, 808. 6 and 1 329. 8 mA·h/g, respectively. After 40 cycles, the discharge capacity remains 743 mA·h/g, which is 97. 5 % of the capacity of the second cycle.
