Graphene materials for lithium-sulfur batteries

Lithium-sulfur (Li-S) batteries are one of the advanced energy storage systems with a variety of potential applications. Recently, graphene materials have been widely explored for fabricating Li-S batteries because of their unique atom-thick two-dimensional structure and excellent properties. This review article summarizes the recent achievements on graphene-based Li-S batteries, focusing on the applications of graphene materials in sulfur positive electrodes, lithium negative electrodes, and as inter layers. The challenges and perspectives of Li-S batteries with graphene materials are also discussed. (C) 2015 Elsevier B.V. All rights reserved.
