New Composite Cathode Materials for Li/S Batteries: A Review

This paper reviews the state-of-art of composite cathode materials for the applications in lithium/sulfur (Li/S) batteries. An attempt is made to highlight those key issues in previous work that have stimulated further research toward practical application of Li/S batteries. Detailed information on the advanced developments on carbon and polymer composite cathodes are presented. Their implementation holds the greatest promise in a number of applications ranging from portable electronics to electric vehicles. Fundamental scientific advances in understanding the reactions occurring in the cells as well as new materials are key to overcoming all the drawbacks related to Li/S batteries. In this review article we focus on some of the recent achievements in boosting the cyclability, power density and performance of Li/S batteries through the development of new cathode composite materials.
