▎ 摘　　要

Nanostructured graphene electrodes generally have a low density, which can limit the volumetric performance for energy storage devices. The liquid-phase mild reduction process of graphene oxide sheets is combined with the continuous aerosol densification process to produce high-density graphene agglomerates in the form of microspheres. The produced graphene assembly shows the cabbage-like morphology with a high density of 0.75 g cm(-3). In spite of such high density, the cabbage-like graphene microspheres have narrow-ranged mesopores and a high surface area. The cabbage-like graphene microsphere exhibits both high gravimetric and volumetric energy densities due to the optimized microstructure, which shows a high gravimetric capacitance of 177 F g(-1) and volumetric capacitance of 117 F cm(-3) in supercapacitors. As a cathode for lithium-ion capacitors, the cabbage-like graphene delivers a reversible capacity of approximate to 176 mAh g(-1). The stacking-control approach provides a new pathway to control the microstructure of the graphene assembly and corresponding charge storage characteristics for energy storage applications.
