摘要	A novel unique C@SnS2 core-shell structure composites consisting of well-dispersity carbon microspheres and ultrathin tin disulfide nanosheets were successfully synthesized for the first time through a simple solvothermal method. The thin SnS2 nanosheets grew onto the carbon microspheres surfaces perpendicularly and formed the close-knit porous structure. When it was used as anode materials for lithium-ion batteries, the hybrid C@SnS2 core-shell structure composites showed a remarkable electrochemical property than pure SnS2 nanosheets. Typically, the hybrid composites with SnS2 nanosheet shells and carbon microsphere's core exhibited an excellent initial discharge capacity of 1611.6 mAh/g. Moreover, the hybrid composites exhibited capacities of 474.8-691.6 mAh/g at 100 mA/g over 50 battery cycles, while the pure SnS2 could deliver capacities of 243-517.6 mAh/g in the tests. The results indicated that the improvement of lithium storage performance of the core-shell structure C@SnS2 anode materials in terms of rate capability and cycling reversibility owing to the introduction of the smooth carbon microspheres and special designing of core-shell structure.
