Lithium-sulfur (Li-S) batteries have attracted much attention for its high energy density, low cost and environmental friendliness. However, they suffer from short life cycle, low columbic efficiency, and safety issues. Through summarizing and outlining the effective strategies to solve the above challenges, in this review, the recent progresses in the sulfur/carbon cathode materials and the corresponding high safety electrolytes towards advanced Li-S batteries are presented. Some potential issues and possible developmental directions are also discussed.
