Abstract:
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.
