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

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.
