Flexible TiO₂/SiO₂/C Film Anodes for Lithium‐Ion Batteries

Abstract

Abstract Flexible TiO 2 /SiO 2 /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 TiO 2 /SiO 2 /C films have the potential to serve as electrodes for flexible LIBs, owing to their flexibility and excellent electrochemical performance.
