▎ 摘  要

NOVELTY - The process involves subjecting a graphene dispersion to a forced assembly procedure. Multiple graphene sheets are forced to assemble into an electrolyte-impregnated laminar graphene structure, where multiple graphene sheets are alternately spaced by thin electrolyte layers, comprising thickness from 0.4 nm to 10 nm, and aligned along desired direction, and the laminar graphene structure has physical density from 0.5 to 1.7 g/cm power of 3 and a specific surface area from 50 to 3,300 m power of 2/g when measured in a dried state of a laminar structure with an electrolyte to be removed. USE - Roll-to-roll process for producing an electrolyte-impregnated laminar graphene structure for use as an electrode of an ultra capacitor electrode (claimed). ADVANTAGE - The process enables providing clear and urgent need for ultra capacitors with high active material mass loading, active materials with a high apparent density, high electrode thickness, high volumetric capacitance, and high volumetric energy density. DETAILED DESCRIPTION - The graphene sheets are selected from a pristine graphene or a non-pristine graphene material. An INDEPENDENT CLAIM is also included for an ultra capacitor electrode. DESCRIPTION OF DRAWING(S) - The drawing shows a flow diagram illustrating a process for producing exfoliated graphite products along with a process for producing pristine graphene foam or graphene oxide foams.
