英文摘要	There are growing research interests in developing high-performance energy storage systems to meet the demands for large-scale and sustainable energy storage. The lithium-sulfur (Li-S) batteries have drawn numerous attentions due to their exceptionally high energy density compared with other batteries. However, achieving the high capacities with long-term cycle stability and retaining an essentially high sulfur loading remains a tremendous challenge for the designs of Li-S batteries. Graphene is regarded as a very suitable and promising addition to the compositions for Li-S batteries due to its unique two dimensional (2D) structure, high conductivity and superior mechanical flexibility. Besides, the functional groups of graphene surface can be tuned flexibly to immobilize the S/Li2Sx on the graphene surface during the cycling process. In this review, the development of graphene-sulfur composites and their applications in Li-S batteries are discussed. The attempts are also devoted to the synthesis approaches of various graphene-based sulfur composites, the graphene-sulfur interaction and the impacts on the electrochemical performances as well as the major issues of Li-S batteries.; ARC Discovery Grants from Australian Research Council; Beijing Project of Scienc and Technology [Z141100003814012]; NSFC-RGC Joint Research Scheme [51361165201]; NSFC [51125001, 51172005]; Doctoral Program of the Ministry of Education of China [20120001110078]; Opeing Funds of National Laboratory of Molecular Science and Key Laboratory of Functional Inorganic Material Chemistry (Heilongjiang University); Ministry of Education of China; SCI(E); 中国科学引文数据库(CSCD); REVIEW; s.zhang@griffith.edu.au; hou@pku.edu.cn; 1,SI; 11-31; 34
