Özet

Nanofibers provide high surface area to volume ratio, vectoral conduction, fast ionic diffusion, and short pathways for sodium ions. Titania nanofibers exhibit excellent electrochemical performance when used for sodium-ion storage. One-dimensional titania nanofiber was synthesized by an electrospinning process as an anode material for high capacity sodium-ion batteries. The electrochemical kinetics of titania nanofiber for sodium-ion storage were examined. Titania nanofiber exhibited pseudocapacitive capacitive properties with high rate performance, giving capacity of 97 mA h g−1 after 1000 cycles with a current density of 1000 mA g−1. Even when current rate returned to the initial current density of 50 mA g−1, titania nanofiber electrode capacity climbed to 206 mA h g−1 again without capacity fading, which indicated good rate performance, superior sodium insertion/extraction reaction, and high reversible capacity.
