Preparation of SnS/graphene nanocomposites from Sn/graphene for superior reversible lithium storage.

SnS/graphene nanocomposites have been prepared through a facile solvothermal reaction with Sn/graphene as the precursor. SnS particles are homogeneously sandwiched between graphene nanosheets. The electrochemical performances of the materials have been evaluated by cyclic voltammetry and galvanostatic discharge/charge cycling. Results show that the nanocomposites exhibit superior reversible lithium storage performance. The strategy presented in this work may provide an easy way for the fabrication of other metal sulfide/graphene nanocomposites. [ABSTRACT FROM AUTHOR]
