PURPOSE:To manufacture thinly formed polarized electrodes that are linked to a reduction in the height of the title capacitor by a method wherein a kneaded matter of carbon powder, a fluorine-containing polymer resin and a liquid lubricant is preformed into a sheet shape, the lubricant is removed and the preformed matter is molded by a rolling roll in a prescribed thickness. CONSTITUTION:An activated carbon fiber made using polyacrylonitrite, for example, consisting of C fine powder and a F-containing polymer resin as its raw material is powdered and prescribed parts weight of a liquid lubricant, such as propylene glycol, is added to 100 parts weight of thew activated carbon powder made to pass through a prescribed mesh and both are mixed by using a spiral mixer. Then, prescribed parts weight of a PTFE aqueous dispersion in terms of solid content, for example, is added to this mixture and both are kneaded to obtain a rubber-like viscous intimate mixture. This intimate mixture is rolled by a roll to obtain a sheet-type preformed material 21. Then, the material 21 is formed thinly by a rolling roll 22 heated at temperature of 90 to 120 deg.C, for example, and a sheet 23 of a prescribed thickness is manufactured. Polarized electrodes 4a and 4b that are linked to a reduction in the height of a capacitor are formed of this sheet and the electrical double layer capacitor 1 is manufactured. |
