Multichannel hollow TiO_2 nanofibers fabricated by single-nozzle electrospinning and their application for fast lithium storage

摘要

Multichannel hollow TiO_2 nanofibers were synthesized via a facile single-nozzle electrospinning method based on phase-separation mechanism. Compared to normal TiO_2 nanofibers, hollow TiO_2 with higher surface area gave rises to a higher surface contribution and ensured a short diffusion path for ion transport. Thus hollow TiO_2 demonstrated superior cyclic ability and excellent rate capability.
