Ultrasmall SnS₂nanoparticles anchored on well-distributed nitrogen-doped graphene sheets for Li-ion and Na-ion batteries

Abstract

SnS₂–NGS hybrid materials: ultrasmall SnS₂–NGS hybrids have been first synthesized by a convenient annealing–hydrothermal-combined route. The excellent Li and Na storage ability is attributed to the unique structure of SnS₂–NGS and the synergistic function between NGSs and SnS₂.
