Synthesis and Electrochemical Properties of TiO₂/C Nano-Fiber Composite

A nano-(TiO₂/C) composite was synthesized using electrospinning method. The thermal analysis was used to determine content of carbon in TiO₂/C composite. The composite (TiO₂/C) was characterized by XRD, the particle size and shape of the (TiO₂/C) composites have been observed by SEM and TEM techniques. The results showed that the TiO₂/C composite takes on nanofiber morphology and the diameter of nanofibers distributed from 50 to 300 nm. The electrochemical properties of the TiO₂/C composite were also investigated. The TiO₂/C composite as an anode material has both high initial discharge capacity (900 mAh · g^–1) and good cycle performances in a testing cells working at room temperature in 3.0 to 0.01 V potential window. The discharge capacity of the TiO₂/C composite was retained at 420 mAh/g after 50 cycles. The reason for TiO₂/C to behave good electrochemical properties is also discussed.
