Abstract

The single-layer graphene usually aggregates and form irreversible multilayer graphene sheets due to the Van Der Waals interaction between the neighboring sheets, and the agglomeration leads to a substantial loss of effective surface area for graphene in the solid state. This affects the graphene's applications where high surface area is the prerequisite. Therefore, the creation of intrinsically ultrahigh surface area graphene in the solid state is paramount significance. In this work, the functionalized hydrophilic carbons were used as the spacer for the preparation of the graphene composites, and the surface area can reach as high as 1256 m2/g with 1% content of functionalized carbon blacks. A specific capacitance of as high as 324.6 F/g at a current density of 0.3 A/g was achieved over the graphene composites. ©The Electrochemical Society.
