Abstract:
Provided is a supercapacitor comprising an anode, a cathode, an ion-permeable separator disposed between the anode and the cathode, and an electrolyte in ionic contact with the anode and the cathode, wherein at least one of the anode and the cathode contains multiple graphene sheets spaced by cellulosic nanofibers and has a specific surface area from 50 to 3,300 m 2 /g. Also provided is a process for producing an electrode for such a supercapacitor having a large electrode thickness, high active mass loading, high tap density, and exceptional energy density.

Claim (Index 24):
A process of producing the supercapacitor electrode of  claim 14 , said process comprising (a) preparing a graphene dispersion having multiple isolated graphene sheets and cellulosic nanofibers dispersed in a liquid or gel electrolyte; and (b) subjecting said graphene dispersion to a forced assembly procedure, forcing said multiple graphene sheets and cellulosic nanofibers to assemble into an electrolyte-impregnated laminar graphene structure, wherein said multiple graphene sheets are alternately spaced by thin electrolyte layers having a thickness from 0.4 nm to 10 nm and having cellulosic nanofibers dispersed in said thin electrolyte layers and said multiple graphene sheets are substantially aligned along a desired direction, and wherein said laminar graphene structure has a physical density from 0.5 to 1.7 g/cm 3  and a specific surface area from 50 to 3,300 m 2 /g, when measured in a dried state of said laminar structure with said electrolyte removed.
