摘　　要：锂硫电池由于具备价格低廉、环境友好、理论比能量与比容量较高等特点,有望成为继锂离子电池之后又一高性能清洁电源体系。近年来,锂硫电池取得了一系列的研究成果,但目前其商业化道路仍困难重重。活性物质硫的穿梭效应、绝缘性以及在充放电过程中的体积膨胀均是制约锂硫电池获得高电化学性能的主要因素。本文从材料角度概述锂硫电池正极材料的研究进展,包括碳/硫复合材料、过渡金属化合物/硫复合材料和导电聚合物/硫复合材料等,并对硫正极的未来发展进行了展望。Lithium sulfur batteries are expected to become another new high performance clean energy system after lithiumion batteries due to the low price,environment friendship,high theoretical specific energy and specific capacity.In recent years,lithium-sulfur batteries have achieved series of research achievements,but its commercialization is still difficult.The shuttle effect,insulation and volume expansion of active sulfur during charging and discharging are the main factors that restricting the high electrochemical performance of lithium sulfur batteries.This work summarizes the research progress of cathode materials for lithium sulfur batteries including carbon/sulfur composites,transition metal compounds/sulfur composites and conductive polymer/sulfur composites.And the future development of sulfur cathode is prospected.
