Three-dimensional network aluminum porous body for current collector, electrode using the aluminum porous body, non-aqueous electrolyte battery using the electrode, non-aqueous electrolyte capacitor, and lithium ion capacitor

摘要

An object of the present invention is to provide an aluminum porous body for a current collector that has a reduced electrical resistivity and an improved current collecting property, and an electrode, a nonaqueous electrolyte battery, a capacitor, and a lithium ion capacitor using the same. The sheet-like three-dimensional reticulated aluminum porous body of the present invention is a three-dimensional reticulated aluminum porous body for current collectors having an electrical resistivity in the in-plane direction and thickness direction of 0.5 mΩcm or less. The thickness of the oxide film on the surface of the aluminum skeleton constituting the aluminum porous body is preferably 5 nm or more and 200 nm or less.
