▎ 摘　　要

NOVELTY - The electrode has solid graphene foam impregnated with liquid or gel electrolyte. The foam is composed of multiple pores and pore walls. The pore walls contain pristine graphene material having zero non-carbon elements, or non-pristine material having 0.001-5 wt.% non-carbon elements. USE - Electrode for super-capacitor (claimed), such as used in hybrid electric vehicles. ADVANTAGE - Enables producing a supercapacitor cell having a high electrode thickness, high active material mass loading, low overhead weight and volume, high volumetric capacitance, and high volumetric energy density, by comprising the solid electrode foam. The cellular structure in a matrix is typically created for reducing density, increasing thermal resistance and acoustic insulation, while increasing the thickness and relative stiffness of the original polymer. DETAILED DESCRIPTION - The electrode has solid graphene foam impregnated with liquid or gel electrolyte. The foam is composed of multiple pores and pore walls. The pore walls contain pristine graphene material having zero non-carbon elements, or non-pristine material having 0.001-5 wt.% non-carbon elements. The non-pristine graphene material is selected from graphene oxide, reduced graphene oxide, graphene fluoride, graphene chloride, graphene bromide, graphene iodide, hydrogenated graphene, nitrogenated graphene, chemically functionalized graphene, or a combination. The foam has physical density of 0.01 to 1.7 grams per cubic centimeter, specific surface area from 50 to 3300 square meters per gram, thermal conductivity of 200 watts per meter-Kelvin per unit of specific gravity, and or electrical conductivity of 2000 Siemens per centimeter per unit of specific gravity, when measured in dried state without electrolyte. An INDEPENDENT CLAIM is also included for a super-capacitor.
