TiO₂ hybrid nanocomposites are promising electrode materials for lithium‐ion batteries because of the large specific capacity, excellent rate capability, and high cycling stability. We have developed an effective facile incipient wetness impregnation method that can be used to fabricate novel mesoporous MoS₂–TiO₂ fibrous nanocomposites. The MoS₂–TiO₂ nanocomposites exhibited notable electrochemical performance with a high capacity of 120 mA h g⁻¹ at a rate of 40 C and long‐term, stable capacity of 124 mA h g⁻¹ with a capacity retention of 75.2 % after 1000 cycles. These results suggest that the structure of mesoporous TiO₂ nanofibers composited with a thin, uniform, well‐dispersed MoS₂ layer improve the rate performance and cycling stability. Such good performance may be derived from the dispersed MoS₂ layer, which accelerates the surface electrochemical reactions and offers a stable structure.

用于超稳定锂离子电池阳极的介孔MoS2-TiO2纳米纤维的简便合成

TiO ₂杂化纳米复合材料因其大的比容量，出色的倍率性能和高循环稳定性而成为有前景的锂离子电池电极材料。我们已经开发出一种有效的，容易的湿润浸渍方法，可用于制造新型的介孔MoS ₂ -TiO ₂纤维纳米复合材料。MoS ₂ -TiO ₂纳米复合材料表现出显着的电化学性能，在40 C的速率下具有120 mA h g ^-1的高容量，并且在1000次循环后具有124 mA h g ^-1的长期稳定容量，容量保持率达75.2％ 。这些结果表明介孔TiO ₂的结构纳米纤维复合有一层薄而均匀且分散良好的MoS ₂层，可改善速率性能和循环稳定性。可以从分散的MoS ₂层获得这种良好的性能，该MoS ₂层可以加速表面电化学反应并提供稳定的结构。
