石墨烯在锂硫电池中的应用研究进展

Rechearch progress of graphene application in lithium sulfur battery

石墨烯只有碳原子厚度并有着强大的碳键网络结构,具有较高的电导率、高比表面积、化学性能好,在锂硫电池中有着广阔的应用前景。主要论述了石墨烯与S的复合物以及经氮掺杂石墨烯与S的复合物在改善锂硫电池电化学性能方面的研究进展,并对目前存在的问题和下一步的工作方向做出分析与展望。

Graphene is a flat sheet of carbon just one atom thick,it also has a strong carbon bonds network struc ture. In addition, graphene has the high electrical conductivity, high specific surface area and good chemical performance, so it has a promising future in application of lithium sulfur batteries. The application of grapbene, nitrogen-doped graphene and their sulfur composites used as cathode materials in lithium sulfur battery was mainly discussed. The existing problems and the prospects were made accordingly.
