A versatile strategy for ultrathin SnS2 nanosheets confined in a N-doped graphene sheet composite for high performance lithium and sodium-ion batteries

Abstract

In this work, few-layer SnS₂ nanosheets confined in a nitrogen-doped graphene sheet composite (SnS₂/NGS) are successfully synthesized via a facile thermal decomposition method. SnS₂/NGS demonstrates sufficient nitrogen-doping and full graphene encapsulation. When evaluated as an anode material for lithium/sodium-ion batteries, it exhibits an excellent electrochemical performance.
