COATED ELECTRODE AND ORGANIC ELECTROLYTE CAPACITOR

摘要

A capacitor electrode which can be industrially manufactured and has a high conductivity, high strength and excellent uniformity is provided. A capacitor using such capacitor electrode is also provided. A coated electrode is provided with a collector composed of an aluminum etching foil, which has a thickness of 20-45µm, an apparent density of 2.00-2.54g/cm³ and many through holes that penetrate the front and rear surfaces having an air permeability of 20-120s; and an electrode layer, which is formed by coating the collector with a coating material containing a substance that can reversibly support lithium ions and anions as an active material.
