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 22):
A process of producing the supercapacitor electrode of  claim 13 , said process comprising a) dispersing said multiple graphene sheets, said cellulosic nanofibers, an optional conductive additive, and an optional resin binder in a liquid medium to form a graphene slurry; b) dispensing and depositing said graphene slurry onto a surface of a solid substrate or a current collector and forming a wet graphene layer thereon which is optionally subjected to a compression treatment to align graphene sheets along a desired direction; c) at least partially removing said liquid medium from said wet graphene layer to form a dry graphene layer wherein multiple graphene sheets are spaced by said cellulosic nanofibers to form said supercapacitor electrode, and d) an optional compression treatment to increase a density of said supercapacitor electrode.
