【Abstract】 Recent progress in research on organic sulfide electrode materials for lithium-ion batteries,which are new type cathode materials with 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.更多还原
