摘　　要：硫正极材料具有比容量高、资源丰富、环境友好等特点,由它与锂金属负极组成锂硫电池是一种极具应用前景的高能量密度的电池体系,在市场上有着极大的发展空间。硫基正极材料作为锂硫电池的重要组成部分,是提高电池性能的关键之一,也是目前的研究重点。然而锂硫电池还存在着一些比较严重的问题,如硫的导电性差、"穿梭效应"和锂晶枝等。本文综述了近几年国内外锂硫电池硫正极材料在单质硫、金属硫化物和有机硫化物三个方面的最新研究进展,并展望了锂硫电池硫正极材料的发展方向。Sulfur cathode material has the advantages of high specific capacity, abundant resources and environmental benignity. Lithium-sulfur battery based on sulfur cathode and lithium metal anode is regarded as a promising battery system with high energy density, which would have a great space for development in the market. Sulfur cathode material, as one of the essential ingredients for lithium-sulfitr battery, is the key to improve the battery performance, and also one of the current research focus. However, there are still some serious problems for lithium-sulfur battery, such as poor conductivity of sulfur, shuttle effect and lithium dendrite. In this review, the recent research progress at home and abroad of sulfur cathode materials, including elemental sulfur, metal sulfides and organic sulfides are introduced, and their development trend is also prospected.
