  • Patent number: 6917094
    Abstract: 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 ?m, not less than 100,000 dimples having a largest outer diameter in a range of 4 to 10 ?m and a depth in a range of 4 to 15 ?m 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.

  • Publication number: 20040164441
    Abstract: 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.
