Electrospun SnO2 and TiO2 Composite Nanofibers for Lithium Ion Batteries.

Highlights: [•] We prepared three types of SnO2/TiO2 composite nanofibers via a facile electrospinning method. [•] Both SnO2 and TiO2 in these fibers are identified as a rutile phase by XRD and Raman Spectroscopy. [•] Composite nanofibers show superior electrochemical performance to pure TiO2 and SnO2fibers. [•] The enhanced cycling stability is due to the space confinement provided by the stable TiO2 matrix. [ABSTRACT FROM AUTHOR]
