Tin-based composites are promising anode materials for high-performance lithium-ion batteries (LIBs); however, insufficient conductivity, as well as fatal volume expansion during cycling lead to poor electrochemical reversibility and cycling stability. In this work, we demonstrate the lithium-ion storage behaviors of SnS₂ anode material deposited on different electrode supports. The SnS₂ grown on 3D hierarchical carbon nanotube-carbon cloth composites (SnS₂-CNT-CC) shows superior capacity retention and cycle stability, compared to that on planar Mo sheets and carbon cloth. The specific capacity of SnS₂ on Mo, CC, and CNT-CC is around 240, 840, and 1250 g⁻¹, respectively. The SnS₂-CNT-CC electrode outperforms in the cyclic performance and rate capability compared to other electrode configurations due to the multi-electron pathway and high surface area derived from 3D hierarchical CNT-CC electrode support. Furthermore, a significant decrease in the charge transfer resistance is observed by utilizing 3D hierarchical CNT-CC electrode support. The use of 3D hierarchical structures as electrode support could be the best alternative to enhance the electrochemical performances for the next generation LIBs.

锡基复合材料是用于高性能锂离子电池（LIB）的有前途的阳极材料。然而，电导率不足以及循环过程中致命的体积膨胀会导致不良的电化学可逆性和循环稳定性。在这项工作中，我们证明了沉积在不同电极支架上的SnS ₂阳极材料的锂离子存储行为。所述SNS ₂生长在3D分层碳纳米管-碳布复合材料（的SnS ₂ -CNT-CC）显示出优异的容量保持和循环稳定性，相比于上平面沫片和碳布。SnS ₂在Mo，CC和CNT-CC上的比容量分别约为240、840和1250 g ^-1。SnS ₂-CNT-CC电极的循环性能和倍率性能优于其他电极配置，这归因于多电子路径和源自3D分层CNT-CC电极支架的高表面积。此外，通过利用3D分层CNT-CC电极支架，可以观察到电荷转移电阻的显着降低。使用3D分层结构作为电极支撑可能是增强下一代LIB电化学性能的最佳选择。
