Abstract: With the world energy shortage crisis becoming more and more serious, the development of renewable energy has become an inevitable trend, and the research of energy storage system has become a key issue. Lithium-ion battery plays an important role in electronic equipment, but its low theoretical specific capacity makes it difficult to meet the needs of large scale electronic equipment. With theoretical specific energy density (2 600 Wh·kg-1) and theoretical specific capacity (1 675 mAh·g-1) several times higher than those of lithium-ion battery, source-abundance and low price of sulfur, lithium-sulfur battery is a very promising energy storage device. Cathode materials have an important impact on the performance of lithium-sulfur batteries, which have been widely studied. In this paper, the recent research progress of sulfur/carbon composites, sulfur@carbon/metal compounds composites, sulfur/heteroatom doped carbon composites and sulfur/carbon composites loaded with catalysts in lithium-sulfur batteries was reviewed, and their future development was prospected.

Key words: lithium-sulfur battery, sulfur cathode, compound material, battery structure, electrochemical performance
