METHOD FOR PRODUCING ELECTRODE FOR CAPACITOR

摘要

The present invention provides a method of producing an electrode for electric double layer capacitor, which yields the electrode having excellent electrode characteristics with good production suitability, using a coating material exhibiting a good dispersion state. A method of producing an electrode for a capacitor, the method comprising the steps of: applying an undercoat layer coating material which comprises at least electrically conductive particles, a binder and a solvent onto the current collector to form the undercoat layer; and applying an electrode layer coating material which comprises at least a carbon material, a binder and a solvent onto the undercoat layer to form the electrode layer. In the preparation of the undercoat layer coating material and/or in the preparation of the electrode layer coating material, dispersing treatment is conducted with ceramic beads as a dispersing medium.
