Sodium Ion Capacitors: The Interplay of Oxygen Functional Groups and Folded Texture in Densified Graphene Electrodes for Compact Sodium‐Ion Capacitors (Adv. Energy Mater. 11/2018)

In article number 1702395, Quan-Hong Yang, Da-Wei Wang and co-workers, successfully utilize graphene oxides as building blocks to construct highly folded graphene electrodes for ultrafast and high-volumetric sodium-ion capacitors (SICs). In addition, the significant interplay of both oxygen functional groups and folded texture in highly folded graphene electrodes for compact sodium storage is explicitly uncovered.
