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 capacity and high power density, simultaneously.
