Through a gelation–solvothermal method without heteroadditives, Cu–Sn–S composites self-assemble to form nanotubes, sub-nanotubes, and nanoparticles. The nanotubes with a Cu3–4SnS4 core and Cu2SnS3 shell can tolerate long cycles of expansion/contraction upon lithiation/delithiation, retaining a charge capacity of 774 mAh g–1 after 200 cycles with a high initial Coulombic efficiency of 82.5%. The importance of the Cu component for mitigation of the volume expansion and structural evolution upon lithiation is informed by density functional theory calculations. The self-generated template and calculated results can inspire the design of analogous Cu–M–S (M = metal) nanotubes for lithium batteries or other energy storage systems.

具有高（脱）锂化性能的自组装Cu-Sn-S纳米管
通过没有杂化添加剂的胶凝-溶剂热法，Cu-Sn-S复合材料可以自组装形成纳米管，亚纳米管和纳米颗粒。具有Cu 3–4 SnS 4核和Cu 2 SnS 3壳的纳米管在锂化/脱锂化时可耐受长周期的膨胀/收缩，从而保持了774 mAh g –1的充电容量。200次循环后，初始库仑效率高达82.5％。密度泛函理论计算表明，铜成分对于减轻锂化时的体积膨胀和结构演化的重要性。自生成的模板和计算结果可以启发锂电池或其他储能系统的类似Cu–MS–M（M =金属）纳米管的设计。
