Current collector using three-dimensional network aluminum porous body, electrode using the current collector, non-aqueous electrolyte battery using the electrode, capacitor using non-aqueous electrolyte, lithium ion capacitor, and electrode manufacturing method

摘要

An object of this invention is to provide the electrode using the electrical power collector which consists of an aluminum porous body suitable for the electrode for nonaqueous electrolyte batteries, and the electrode for capacitors, and the manufacturing method of this electrode. In the current collector of the present invention, a band-like compressed portion compressed in the thickness direction is formed at one end of the three-dimensional network aluminum porous body, and a tab lead is joined to the compressed portion by welding. The width of the compression part is 2 to 10 mm. The electrode is obtained by filling the current collector with an active material.
