Abstract
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 ∼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 ∼26 nm by adjusting the precursors, solvents and source concentrations. The nanostructural effects are investigated in terms of electrochemical and rate-capability properties.
