Abstract

Nanofiber structured Na2Ti3O7 was synthesized via electrospinning process which was further used as an anode material for sodium-ion batteries for the first time. One-dimensional construction of Na2Ti3O7 composite could contribute to better electrochemical activity. It was demonstrated that the capacity of Na2Ti3O7 nanofibers was significantly improved to 257.8 mAh g(-1) at 30 mA g(-1). Furthermore, the rate capability of Na2Ti3O7 nanofibers was significantly enhanced, showing charge capacities were 161.8, 116.5, and 72.4 mAh g(-1) at 100, 200, and 400 mA g(-1), respectively. Therefore, improved specific capacity and rate capability made Na2Ti3O7 nanofibers composite as a promising anode material for sodium-ion batteries.
