The Inside Cover picture shows the high‐surface‐area nitrogen‐doped graphene (N‐RGO) used as electrode in an electric double‐layer capacitor (EDLC). We designed an efficient and scalable process for preparing the graphene‐based electrode materials, which, in addition to a large specific surface area, has a high electrical conductivity and very low oxygen content. These impressive properties gave rise to improved electrochemical properties owing to the high specific capacitance, the good rate capability, and the excellent cycling stability for EDLC applications. Furthermore, near‐edge X‐ray absorption (NEXAFS) analysis provided information on the recovery of the conjugated structure of the carbon networks through removal of the oxygen functional groups as well as information about the chemical bonding environments of the nitrogen atoms in high‐surface‐area N‐RGO.
