3D architecture constructed by 2D SnS2-graphene hybrids towards large and fast lithium storage.

3D architecture constructed by 2D hybrids of few-layer SnS 2 nanoplates and graphene has been prepared via a facile solvothermal method using tin tetrachloride, thiourea, graphene oxide nanosheets, and sodium dodecyl sulfonate as starting materials. The sample is characterized by SEM, TEM, XRD, and TG techniques, revealing that the few-layer SnS 2 nanoplates are well dispersed and tightly contacted onto graphene substrates, and the 2D hybrids assembly into 3D architecture. Endowed with the structural and compositional advantages of the specific architecture, the SnS 2 -graphene composite exhibits good electrochemical properties as anode for lithium-ion batteries, including high capacity, good cyclic stability (826 mA h g −1 at current density of 0.5 A g −1 after 200 cycles), and excellent high-rate performance (498 mA h g −1 at 8 A g −1 ).
