| Abstract: |
Ti 2 Nb 10 O 29 is a high-capacity, safe and stable anode material for lithium-ion batteries, but suffers from a poor rate capability. To tackle this issue, nanotechnology is employed, and Ti 2 Nb 10 O 29 hollow nanofibers with an average fiber diameter of ∼500 nm and shell thickness of ∼90 nm are prepared by a facile co-electrospining technique followed by calcination in air. This material exhibits not only a high reversible capacity (307 mAh g −1 at 0.1 C) and durable cyclic stability (0.06% capacity loss per cycle at 10 C over 500 cycles) but also an outstanding rate capability (136 mAh g −1 at 20 C), thereby becoming a promising anode material for high-performance lithium-ion batteries.
