Granules for formation of an electrode of an electric double layer capacitor, manufacturing mehtod thereof, electrode sheet, polarized electrode, and electric double layer capacitor using a polarized electrode

A manufacturing method of granules for formation of an electrode of an electric double layer capacitor, comprising the steps of:

• (a) producing material lumps by kneading materials including an activated material, a conductive filler, and a binder at 50 to 97 mass-%, 1 to 30 mass-%, and 2 to 20 mass-%, respectively, and fibrillating the binder;
• (b) producing crushed granules by crushing the material lumps;
• (c) classifying the crushed granules to remove granules whose diameters are larger than 840 μm;
• and
• (d) classifying the crushed granules to remove granules whose diameters are smaller than 47 μm.

A manufacturing method of a polarized electrode for an electric double layer capacitor for manufacturing a sheet-like polarized electrode for an electric double layer capacitor comprising the steps of:

• mixing and kneading materials including a carbonaceous powder, a conductivity-enhancing agent, and a binder into a kneaded material,
• producing a forming material by converting the kneaded material into granules, and
• forming and rolling the forming material, wherein
• the granules as the forming material produced from the kneaded material are generally glomerate and are in a diameter range that the diameter is larger than or equal to 47 μm and smaller than 840 μm.
