Multichannel hollow TiO2 nanofibers fabricated by single-nozzle electrospinning and their application for fast lithium storage

Multichannel hollow TiO2 nanofibers were synthesized via a facile single-nozzle electrospinning method based on phase-separation mechanism. Compared to normal TiO2 nanofibers, hollow TiO2 with higher surface area gave rises to a higher surface contribution and ensured a short diffusion path for ion transport. Thus hollow TiO2 demonstrated superior cyclic ability and excellent rate capability.

► Multichannel hollow TiO2 nanofibers were fabricated based on phase separation via single-nozzle electrospinning technique.
► Hollow TiO2 nanofibers showed excellent electrochemical performance as anode materials for lithium battery.
► Surface storage played a vital role in achieving such excellent performance.
