THREE-DIMENSIONAL POROUS ALUMINUM MESH, ELECTRODE USING SAME, NONAQUEOUS-ELECTROLYTE BATTERY USING SAID ELECTRODE, AND CAPACITOR AND LITHIUM-ION CAPACITOR USING NONAQUEOUS LIQUID ELECTROLYTE

摘要

The present invention provides: a three-dimensional porous aluminum mesh having a cell diameter that is not uniform in a thickness direction; a collector and electrode using said porous aluminum mesh; and manufacturing methods therefor. This sheet-shaped three-dimensional porous aluminum mesh for use in a collector has a cell diameter that is not uniform in the thickness direction. In particular, if the cross-section of said three-dimensional porous aluminum mesh in the thickness direction is divided into a first region, a second region, and a third region, in that order, the mean of the cell diameters in the first and third regions is preferably different from the cell diameter in the second region.
