A novel layered SnSSe material is designed as a high-performance anode for sodium-ion batteries with characteristics of high capacity, superior cyclability, facile synthetic method, and large-scale production ability. The transformation from bulk SnSSe particles into closely packed nanoplate aggregates with greater resistance to structure pulverization and the partial pseudocapacitive capacity contribution may engender excellent cycling performance and rate capability.
设计了一种新型分层 SnSSe 材料，作为高性能钠离子电池的阳极，具有高容量、优异的循环稳定性、简便的合成方法和大规模生产能力等特点。从块状 SnSSe 颗粒到紧密堆积的纳米片聚集体的转变，增加了结构粉碎的阻力，以及部分赝电容容量的贡献，可能会产生优异的循环性能和倍率性能。
