Abstract: The future development trend in the energy field focuses on green and clean energy. Lithium-sulfur battery has become a new hot spot in battery research due to its advantages of high specific energy and low cost. However, there are still many problems hindering the commercialization of lithium-sulfur batteries, such as the poor conductivity of the positive material sulfur, the shuttle effect of the positive product polysulfide, and the volume expansion of the battery's internal electrodes during the process of charge and discharge. In this study, the research progress of lithium-sulfur battery cathode materials in recent years is reviewed, the application of metal-organic framework compounds, carbon materials and conductive polymers in lithium-sulfur battery cathode materials is discussed, and the development of lithium-sulfur battery cathode materials is prospected.
