THREE-DIMENSIONAL NETWORK ALUMINUM POROUS BODY FOR CURRENT COLLECTOR, AND CURRENT COLLECTOR, ELECTRODE, NONAQUEOUS ELECTROLYTE BATTERY, CAPACITOR AND LITHIUM-ION CAPACITOR, EACH USING ALUMINUM POROUS BODY

摘要

It is an object of the present invention to provide a current collector including an aluminum porous body suitable for an electrode for a nonaqueous electrolyte battery and an electrode for a capacitor electrode, and an electrode using the current collector. In the three-dimensional network aluminum porous body for a current collector of the present invention, when a sheet-shaped three-dimensional aluminum porous body is divided in the width direction into a central region and two end regions with the central region situated therebetween, the weight per unit area of aluminum in the aluminum porous body at the two end regions is larger than the weight per unit area of aluminum in the aluminum porous body at the central region.
