Organic sulfides are recognized as the most promising cathode materials for lithium-sulfur batteries due to their high capacities, abundant resources and adjustable structures. Organic sulfides have a variety of superior features with respect to the diversity of structural designs, superior lithium storage properties and reaction mechanisms. In this review, recent development on organic sulfides in lithium sulfur batteries was represented, the latest progress of researches on small molecule polysulfides, polysulfides and vulcanized polymers was described, and their structure characteristics and electrochemical mechanisms were illustrated. In addition, the relationship between electrochemical performance of organic sulfides and their structure design as well as functional groups was also summarized. The future prospect of organic sulfides was given for next generation energy storage systems.
