Abstract

Abstract Lithium sulfur batteries are considered to hold great potential for the next generation of high energy density portable electronic devices or vehicles, however, they are hindered by their poor cycling stability. Recently, more attention have been paid on the mechanism study, trying to reveal and solve the major existing issues, furthermore, to guide and improve the design of new lithium sulfur cells with high performance. Here, a novel route is developed to synthesize light-weight and mechanically stable reduced graphene oxide (rGO) rGO/carbon monoliths for the application in lithium sulfur (Li/S) cells. This cathode material is characterized by a hierarchical pore structure with a {BET} surface area of 1029 m
