摘要

不受控制的多硫化物穿梭和锂枝晶生长极大地阻碍了锂-S 电池的实际应用。这些问题可以通过构建人工层来缓解，人工层可以固定可溶性多硫化物并调节锂+通量。在这里，我们通过分子插层技术制造了一种层状扩展的锂蒙脱石，作为锂-S 电池的双重调节剂。这种亲锂蒙脱石具有有序且扩展的锂+扩散通道，显示出较高的转移数，并促进了锂的均匀沉积。此外，它对多硫化物的适度吸附与有利的锂扩散行为相结合，增强了硫物种的氧化还原动力学。这种独特的结构可延长锂-S 电池在 0.5C 下 1000 次循环的寿命，且每次循环的容量衰减较低，仅为 0.04%。

Ordered and Expanded Li Ion Channels for Dendrite‐Free and Fast Kinetics Lithium–Sulfur Battery

The uncontrolled polysulfide shuttling and lithium dendrite growth greatly impede the practical implementation of Li–S batteries. These issues can be alleviated by constructing an artificial layer that immobilizes soluble polysulfides and regulates Li+ flux. Here, a layer‐expanded lithium montmorillonite is fabricated through molecular intercalation to serve as a dual regulator for Li–S batteries. The lithiophilic montmorillonite, with its ordered and expanded Li+ diffusion channels, exhibits a high transference number, and promotes homogeneous Li deposition. Additionally, its moderate adsorption of polysulfides, combined with favorable Li diffusion behavior, enhanced the redox kinetics of sulfur species. This unique structure enables a prolonged lifespan of 1000 cycles at 0.5C with a low capacity decay of 0.04% per cycle for practical Li–S batteries.
