In Situ Sulfur Reduction and Intercalation of Graphite Oxides for Li‐S Battery Cathodes

Abstract

Sulfur intercalated expanded graphite for Li-S battery cathodes is synthesized by in situ one-step sulfur reduction and intercalation of graphite oxide (GO). The unique structural reduced graphene oxide (RGO)/S nanocomposite cathodes exhibit high capacity, super rate capability, and long cycle stability. The exceptional electrochemical properties of the RGO/S composites plus their simple fabrication make this class of materials attrac­tive for further investigation in Li-S batteries applications.
