摘　　要：有机硫化物电极材料是一类新型高比容量的储能材料,通过S—S键的可逆断裂与键合进行释能与储能,主要应用于锂离子电池的正极。该材料包括有机二硫化物、有机多硫化物和硫化聚合物等。本文综述了有机硫化物电极材料的研究现状,分析了各种材料的优势与不足,并展望了其发展趋势。如何提高现有材料的比容量并改善其循环性能是目前的研究重点。Recent progress new type cathode materials with in research on organic sulfide electrode materials for lithium-ion batteries, which are high specific capacity, including organodisulfide, organomultisulfide and sulfurized polymers, is introduced. Organic sulfides are of electrochemically active due to the chemical reversibility of S--S oxidation and reduction reactions. In this paper the advantages and shortcomings of the electrode materials are discussed, and their development are also previewed. In addition, improving the specific capacity and cycling stability of the materials should be the research priorities.
