The collector body the invention provides a kind of three-dimensional netted aluminum porous body, all employing this aluminum porous body and electrode；And their manufacture method, the emptying aperture diameter of wherein said three-dimensional netted aluminum porous body is uneven in a thickness direction.That is, the emptying aperture diameter of this lamellar in collector body three-dimensional netted aluminum porous body is uneven in a thickness direction.Especially, if the cross section on the thickness direction of described three-dimensional netted aluminum porous body is divided into region 1, region 2 and these three region, region 3 successively, the most preferably, region 1 is different from the emptying aperture diameter in region 2 with the meansigma methods of region 3 hollow hole diameter. |
