A current collector using a three-dimensional network aluminum porous body, electrode using the current collector and non-aqueous electrolyte battery, non-aqueous electrolytic solution capacitor and lithium ion capacitor each using the electrode, and methods of producing the electrode

摘要

It is an object of the present invention to provide an electrode using a current collector made of an aluminum porous body which is suitably used for an electrode for a nonaqueous electrolyte battery and an electrode for a capacitor, and a method for producing the electrode. In the current collector of the present invention, a strip-shaped compressed part compressed in a thickness direction is formed at one end part of a three-dimensional network aluminum porous body and a tab lead is bonded to the compressed part by welding. The width of the compressed part is 2 to 10 mm. Further, the electrode is formed by filling the current collector with an active material.
