Hierarchical non-woven fabric NiO/TiO₂ film as an efficient anode material for lithium-ion batteries

Hierarchical non-woven fabric NiO/TiO₂ film is prepared using a facile two-step synthesis by electrospinning and subsequent hydrothermal reaction to yield TiO₂ film decorated with NiO nanosheets. As an anode material for Li-ion batteries, the NiO/TiO₂ composite exhibits discharge and charge capacities of 1251.3 and 1284.3 mA h g^-1, with good cycling performance and rate capability. Characterization shows that the NiO nanosheets are distributed on the surface of the TiO₂ nanofibers. The total specific capacity of NiO/TiO₂ is higher than the sum of pure TiO₂ and NiO, indicating a positive synergistic effect of TiO₂ and NiO on the improvement of electrochemical performance. The results suggest that non-woven fabric NiO/TiO₂ film is a promising anode material for lithium ion batteries.
