PURPOSE:To provide a solid electrode composition for constituting an electric double layer capacitor of large capacity, which excels in mechanical strength and workability. CONSTITUTION:This solid electrode composition is what is composed by carrying a solid electrolyte and an activated carbon on a conductive or non-conductive woven cloth or unwoven cloth for composition, which is composed by forming into a gel an aprotic organic solvent in which an alkaline metal salt and an ammonium salt are dissalved, by using a copolymer of acrylonitrile and methyl acrylate or methyl methacrylate. Hydroxide group and carboxylic acid group on the surface of an activated carbon, woven cloth and the like reacts to a copolymer to accelerate the gel formation of a solid electrolyte, and an organic solvent with a salt melted inside the fine hole of an activated carbon is effectively held to allow the inner surface of the fine hole to get wet, and an electric double layer is effectively formed along the inner surface of the fine hole in an activated carbon on a large area to obtain a large electric double layer capacity. And an activated carbon and a fixed electrolyte are firmly held on a woven cloth and the like with the reaction between activated carbon particles and also between a woven cloth and the like and a solid electrolyte in an electrode slurry. |
