Flexible TiO2 /SiO2 /C Film Anodes for Lithium-Ion Batteries.

Flexible TiO2 /SiO2 /C films are prepared by using an electrospinning approach and used as self-supporting electrodes for lithium-ion batteries (LIBs), which exhibit excellent high-rate capability with a capacity of 115.5 mAh g-1 at 8 A g-1 (9.8 C rate) and good storage performance. The LIBs also show high long-term cycling stability of 700 cycles at 200 mA g-1 with a capacity of 380.1 mAh g-1 and a high capacity retention of 88.3 %. Thus, the TiO2 /SiO2 /C films have the potential to serve as electrodes for flexible LIBs, owing to their flexibility and excellent electrochemical performance.
