Electrode material; and battery, nonaqueous-electrolyte battery, and capacitor all incorporating the material

Abstract

The invention offers an electrode material that can accomplish both high capacity and high output and a battery, a nonaqueous-electrolyte battery, and a capacitor all incorporating the electrode material. The electrode material has a sheet-shaped aluminum porous body carrying an active material. The above-described aluminum porous body has a skeleton structure that is formed of an aluminum layer and that has a vacant space at the interior. When observed by performing cutting in a direction parallel to the direction of thickness of the sheet, the above-described vacant space in the skeleton structure has an average area of 500 μm2 or more and 6,000 μm2 or less.
