Abstract

TiO₂ nanofibers, TiO₂ hollow nanofibers, and nitridated TiO₂ hollow nanofibers were synthesized using a simple electrospinning method and subsequent nitridation treatment. The nitridated TiO₂ hollow nanofibers showed twice higher rate capability compared to that of pristine TiO₂ nanofibers at 5 C. This improvement is mainly attributed to shorter lithium ion diffusion length and high electronic conductivity along the surface of nitridated hollow nanofibers.
