Abstract

Flexible TiO /SiO /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 at 8 A g (9.8 C rate) and good storage performance. The LIBs also show high long-term cycling stability of 700 cycles at 200 mA g with a capacity of 380.1 mAh g and a high capacity retention of 88.3 %. Thus, the TiO /SiO /C films have the potential to serve as electrodes for flexible LIBs, owing to their flexibility and excellent electrochemical performance.

摘要

采用静电纺丝法制备了柔性TiO/SiO/C薄膜，并将其用作锂离子电池（LIBs）的自支撑电极，该电极在8 A g（9.8 C倍率）下表现出优异的高倍率性能，容量为115.5 mAh g，且具有良好的存储性能。该锂离子电池在200 mA g下还表现出700次循环的高长期循环稳定性，容量为380.1 mAh g，容量保持率高达88.3%。因此，TiO/SiO/C薄膜因其柔韧性和优异的电化学性能，有潜力用作柔性锂离子电池的电极。
