CuSnS, as a modified material for high-capacity tin-based anodes, has great potential for lithium-ion battery applications. The solvothermal method is simple, convenient, cost-effective, and easy to scale up, and has thus been widely used for the preparation of nanocrystals. In this work, CuSnS nanoparticles were prepared by the solvothermal method. The effects of high-temperature annealing on the morphology, crystal structure, and electrochemical performance of a CuSnS nano-anode were studied. The experimental results indicate that high-temperature annealing improves the electrochemical performance of CuSnS, resulting in higher initial coulombic efficiency and improved cycling and rate characteristics compared with those of the as-prepared sample.
作为高容量锡基负极的改性材料，CuSnS在锂离子电池应用方面具有巨大潜力。溶剂热法简单、便捷、成本效益高且易于放大规模，因此已被广泛用于制备纳米晶体。在本工作中，采用溶剂热法制备了CuSnS纳米颗粒。研究了高温退火对CuSnS纳米负极的形貌、晶体结构和电化学性能的影响。实验结果表明，高温退火提高了CuSnS的电化学性能，与制备态样品相比，其初始库仑效率更高，循环性能和倍率性能也得到了改善。
