摘要:
采用溶剂热法制备了二硫化锡/碳(SnS2/C)材料，通过XRD、拉曼光谱(Raman)、TEM、XPS和N2吸附-脱附等手段对材料的物相结构、分子结构、微观形貌、元素组成和比表面积等进行了表征。SnS2/C作为负极材料组装锂离子纽扣电池，研究了材料的电化学性能。结果表明：SnS2/C电极首次放电的比容量高达2 417.15 mAh/g，表现出优于纯相SnS2的电化学性能，这得益于SnS2和C之间的相互作用，C作为载体复合有效提高了SnS2的比表面积，提高了电极反应活性位点的数量，有效抑制了硫化物穿梭效应，界面转移电阻的降低导致导电性提高。SnS2/C电极在1.0 A/g电流密度下循环放电600次的电容保持率达到了70.54%，表现出良好的倍率性能和循环寿命。
Abstract:
Tin disulfide/carbon (SnS2/C) materials were prepared by solvothermal method. The phase structure, molecular structure, microstructure, elemental composition and specific surface area of the materials were characterized by XRD, Raman, TEM, XPS and N2 adsorption-desorption. SnS 2/C was used as an anode material to assemble lithium-ion button batteries, and the electrochemical properties of the materials were studied. The results show that the initial discharge specific capacity of SnS2/C electrode is as high as 2 417.15 mAh/g, which shows better electrochemical performance than that of pure SnS2. This is due to the interaction between SnS2 and C. The composite of C as a carrier effectively increases the specific surface area of SnS 2, increases the number of electrode reaction active sites, effectively inhibits the shuttle effect of sulfides, and reduces the interfacial transfer resistance to improve the conductivity. The SnS2/C electrode has a capacitance retention rate of 70.54% after 600 cycles discharge at a current density of 1.0 A/g, with better rate performance and cycle life
