Facile Solvothermal Synthesis of Flowerlike SnS2 Nanosheets for Enhanced Lithium Ion Storage Property

摘要

Flowerlike SnS2 nanosheets are synthesized by a fast, low-energy, and facile hydrothermal route. Synthetic conditions, such as the sulfur source, reaction temperature, molar ratio of Sn/S in the source material, and reaction time, that vitally affect the morphologies of the final products are investigated. BET measurements show that the flowerlike SnS2 nanostructure has high surface area (71.84 m(2)g(-1)). Furthermore, the treated flowerlike SnS2 architecture as anode material of lithium ion batteries has a relatively large initial reversible capacity of 1470.1 mAhg(-1) and retains a reversible capacity of 604.5 mAhg(-1) after 30 cycles, with enhanced cycling performances at a current density of 200 mAg(-1).
