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.
