摘　　要：通过热解法成功制备出超薄SnS2纳米片嵌入氮掺杂石墨烯复合材料(SnS2/NGS),所制得的SnS2/NGS表现出足够的氮掺杂和石墨烯的包覆.电化学性能数据表明, SnS2/NGS作为锂/钠离子负极材料,具有优异的电化学性能.In this work, few-layered SnS2 nanosheets confined in nitrogen-doped graphene sheets composite(SnS2/NGS) are successfully synthesized by a facile thermal decomposition method. The SnS2/NGS demonstrates sufficient nitrogen-doping and full graphene encapsulation. When evaluated as anode materials for lithium/sodium-ion batteries, it delivers an excellent electrochemical performance.
