Layer‐by‐layer gelation of reduced graphene oxide through spontaneous reduction at a metal surface is developed by S. O. Kim and co‐workers on page 615. This allows 3D shape engineering and arbitrary scaling up, according to need. Gel sheets with a porous hydrated network show excellent energy‐storage performances when they are used as supercapacitor electrodes, demonstrating a high areal capacity...
Site specific electroless gelation enables straightforward solution processing of graphene gel films with ultimate scalability and three‐dimensional shape engineering. Due to the synergistic combination of open porous structure and highly electro‐conductivity graphene gel framework, shape engineered gel films could be exploited for high performance supercapacitor electrode and achieved large energy...
