Abstract
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.
