In article number 1701026, Jiaxing Huang, Quan-Hong Yang, and co-workers, prepare a porous, yet compact, RuO2/graphene composite via a disassembly–reassembly strategy, achieving effective and uniform loading of RuO2 nanoparticles inside the graphene monolith. The disassembly ensures nanoparticle loading into the solid graphene monolith, while the reassembly guarantees a high density, while simultaneously producing unimpeded ion transport channels. The resulting composite possesses a high density, leading to a record volumetric capacitance as high as 1485 F cm−3.
