Abstract

The serious shuttle effect involving lithium polysulfides (LiPSs) stands as a critical obstacle impeding the advancement of lithium‑sulfur batteries (LSBs). In this paper, flexible NbSe₂/carbon nanofibers (CNF) film was fabricated through electrospinning and calcination processes. The NbSe₂/CNF film possesses efficient conductive network and strong chemical-capturing capabilities for LiPSs. Owing to the synergistic combination, the NbSe₂/CNF composite can remarkably alleviate the shuttling behavior of LiPSs. Consequently, the battery integrated NbSe₂/CNFs interlayer achieves a reversible capacity of 762 mAh g^-1 following 300 cycles at 0.5C. Furthermore, it shows superior rate performance, reaching a capacity of 475 mAh g^-1 when subjected to the high rate of 4C. This study offers a reasonable approach for manufacturing flexible interlayers with optimized structures to boost the electrochemical behavior of LSBs.

锂离子电池氧化还原动力学增强的柔性NbSe2/碳纳米纤维。

锂多硫化物（LiPSs）的严重穿梭效应是阻碍锂硫电池（LSBs）发展的关键障碍。采用静电纺丝和煅烧两种工艺制备了NbSe2/ CNF柔性薄膜。NbSe2/CNF薄膜具有高效的导电网络和强大的化学捕获能力。由于协同作用，NbSe2/CNF复合材料可以显著缓解LiPSs的穿梭行为。因此，集成了NbSe2/CNFs中间层的电池在0.5C下循环300次后达到了762 mAh g-1的可逆容量。此外，它表现出优越的倍率性能，在高倍率4C下达到475 mAh g-1的容量。本研究提供了一种合理的方法来制造具有优化结构的柔性中间层，以提高lsb的电化学性能。
