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.
