The cover picture shows the structure of three‐dimensional graphene/Fe 2 O 3 composite as a promising electrode material for supercapacitor, as well as the potential application of supercapacitor in electric automobile. The composites are synthesized via a one‐step reaction between graphene oxide and Fe 2+ at a mild condition. During the reaction, graphene oxide sheets are reduced and self‐assemble into a 3D network, while Fe 2+ is converted into Fe 2 O 3 and deposited onto the graphene network. This structure facilitates the diffusion of the electrolyte and the electron transfer between Fe 2 O 3 and the current collector, thus endowing the composites with high capacitive performance. More details are discussed in the article by Bai et al . on page 67–72.
