SnO2 Nanofibers Prepared by Sol-Gel Template Method

Abstract:

SnO2 nanofibers were successfully prepared in porous anodie aluminum oxide(AAO)template by sol-gel-template method.The microstructures and electrochemical properties of SnO2 nanofibers were studied.SEM images indicate that SnO2nanofibers are uniformly distributed and parallel to each other.The SnO2 nanofiber possesses a tubular structure.The XRD pattem shows that the nanofibers are cassiterite Sn02.Good cycling performance could be obtained when the SnO2 nanofibers were used as electrodes in the Li-ion batteries.The electrodes could deliver high capacity and still retain the ability to discharge and recharge through many cycles.
