Abstract
Uniform Sn/C hybrid core/shell nanocomposites were synthesized by a combination of electrospinning and subsequent thermal treatment in a reducing atmosphere. The particular three-dimensional architecture, consisting of a Sn@C nanoparticle core and porous hollow carbon nanofiber shell, is characterized by many micro/nanochannels, enhanced mechanical support from the three-dimensional hollow carbon shell, and the abundant porous carbon matrix. The as-prepared Sn/C core/shell nanomaterials exhibit excellent electrochemical performance. They display a reversible capacity of 546.7Â mAhgâ1 up to 100 cycles at the current density of 40Â mAgâ1 and good rate capability of 181.8Â mAhgâ1 at 4000Â mAgâ1. These results indicate that the composite could be a promising anode candidate for lithium ion batteries.
