    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： In an electrode for an electric double layer capacitor of the present invention, the peak value of particle size distribution of graphite particles added to a conductive adhesive is in a range of 2.6 to 3.2 μm, not less than 100,000 dimples having a largest outer diameter in a range of 4 to 10 μm and a depth in a range of 4 to 15 μm are formed on the surface of the collector sheet per 1 cm2, and the occupied area of the dimples to the entire surface area of the collector sheet is not more than 50%. By determining the saponification value of polyvinylalcohol which is used as a binder component of the conductive adhesive in a range of 90.0 to 98.5, adhesiveness of the collector sheet and the electrode forming sheet is improved. Furthermore, by substituting H atoms contained in the polyvinylalcohol with Si atoms, adhesiveness of the collector sheet and the electrode forming sheet can be further improved.

    摘要： A polarizing electrode for an electric double layer capacitor has good moldability and is capable of achieving higher density of electrode and higher capacity. An electric double layer capacitor employs the same. The polarizing electrode for an electric double layer capacitor is made of an activated carbon obtained by activating a hard-to-graphitize material (for example, phenol resin) with water vapor, and the activated carbon has a median particle size within a range from 4 μm to 8 μm in the particle size distribution as measured by a laser diffraction method and a benzene adsorption ratio of not less than 47.0% and not more than 60% by weight of activated carbon.
