摘要 能源领域未来发展趋势着重于绿色清洁能源,锂硫电池以其高比能量以及成本低廉等优点,成为电池研究中的新热点。然而,目前锂硫电池仍存在较多问题阻碍其商业化,如正极材料硫导电性能差、正极产物多硫化物的穿梭效应、在充放电过程中,电池内部电极表现出体积膨胀等。本研究综述了近年来锂硫电池正极材料的研究进展,主要讨论了金属有机骨架化合物、碳材料以及导电聚合物在锂硫电池正极材料中的应用,并对锂硫电池正极材料的发展进行了展望。 The future development trend in the energy field focuses on green and clean energy.Lithium-sulfur battery has be⁃come 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 sul⁃fur,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.
