    摘要： A method is provided for optimizing the physical characteristics of a coating solution for a polarizable electrode layer formed on a collector. A first step is carried out to prepare a coating solution that includes porous particles, a fluorine-based binder, a good solvent that dissolves said fluorine-based binder, and a poor solvent that does not dissolve said fluorine-based binder. A second step is carried out to coat a collector with said coating solution to form the polarizable electrode layer on the collector. The viscosity of said coating solution for the polarizable electrode layer is set to between 0.5 to 3.5 Pa·s and a weight ratio (GS/PS) of said good solvent (GS) and said poor solvent (PS) is set to between 60/40 to 80/20. The occurrence of cracks in the polarizable electrode layer and large nonuniformities in the thickness of the polarizable electrode layer can thus be prevented.

    摘要： A method is provided for optimizing the physical characteristics of a coating solution for an undercoat layer formed between a polarizable electrode layer and surface-roughened collector. A first step is carried out to form an undercoat layer on a collector whose surface has been roughened, and a second step is carried out to form a polarizable electrode layer on the undercoat layer. The first step is performed by coating the collector with a coating solution for the undercoat layer that includes electroconductive particles, a binder, and a solvent; the viscosity of the coating solution for the undercoat layer is set to from 0.15 to 0.75 Pa·s, and the weight ratio (P/B) of the electroconductive particles (P) and binder (B) is set to from 20/80 to 40/60. The coating area of the undercoat layer can thereby be adjusted with high precision, and the resistance of the undercoat layer can be reduced.

    摘要： A sheet electrode with a predetermined thickness for an electric double layer capacitor is made by carrying out a roller rolling step in which a long sheet intermediate is made from a material containing a carbonaceous powder, a conductive assistant and a binder and thereafter. The sheet intermediate is passed between a pair of rolling rollers to be wound up by a winding section while being drawn out of a drawing section. The roller rolling step includes drawing the sheet intermediate out of the drawing section under a predetermined tension applied to the sheet intermediate, and controlling a widthwise position of the sheet intermediate immediately before the rolling rollers by an edge position controller, and winding the sheet intermediate rolled by the rollers onto a winding section while the winding section is applying a predetermined pressure to a rolling side drive roller located adjacent to the winding section and rotated at a predetermined speed.

    摘要： By using the polarized electrode for electric double layer capacitor of the present invention, which is produced by mixing powdery activated carbon with a binder, and is characterized by the concentration of an organic compound being not more than 300 (ppm), the amount of organic compounds which remain in the pore of the powdery activated carbon decrease, and a possibility of forming the electric double layer by adsorption of electrolytic ion can be prevented. Thereby, an electric double layer is sufficiently formed inside the pore of the powdery activated carbon, and the diffusion resistance between the powdery activated carbon and the electrolyte becomes low. By constituting as such, an electric double layer capacitor with a large electrostatic capacity and a little internal resistance can be obtained.
