The separator for the electric duplex formation capacitor which possesses roughness and fineness structure and the electric duplex formation capacitor which uses that

摘要

P To provide a separator that has not only improved impregnation properties of an electrolyte and ion mobility as in a conventional separator containing cellulose but also mechanical strength and oxidation-resistant reducing properties. PSOLUTION: In the separator for electric double layer capacitors made of a porous sheet and the porous sheet has a high-density layer with approximately 20-50% porosity and a low-density layer with approximately 50-80% porosity.
