摘要：

Crystalline tin-sulfide nanosheets are synthesized through a one-step solvothermal process and incorporated in the negative electrode material for lithium-ion batteries. SnS2 compounds synthesized in ethylene glycol have an approximately 2 nm-thick nanosheet morphology and exhibit an excellent charge-capacity retention of similar to 95% after 50 cycles between 1.15 and 0 V at 0.5 C (=323 mA g(-1)). The thickness of the nanosheets is varied up to similar to 26 nm by adjusting the precursors, solvents and source concentrations. The nanostructural effects are investigated in terms of electrochemical and rate-capability properties. (C) 2007 Elsevier B.V. All rights reserved.
