Lithium-sulfur battery is a high capacity energy storage system with bright future,and it is considered as the next generation portable energy supply device for electric vehicle(EV)and hybrid electric vehicle(HEV).Through decades of research and development,people understand the system stepwisely.The electrochemistry mechanism of sulfur cathode is very complex and hard to examine,which is the key point to develop lithium-sulfur battery.Although there are many unknown mechanism in the electrochemical process of charge/discharge of the lithium sul-fur battery,some achievements have been made on the development of cathode materials which provide various sources to study.The achievements on lithium sulfur battery in the past decade from the respects of lithium sulfur battery system and cathode materials are reviewed in this pa-per.The weaknesses are revealed and the future is prospected.
