Abstract
A micro-denier fiber of less than approximately 2.0 microns is coated in a valve metal to a metal thickness of approximately 0.2 to 2.0 microns. In one embodiment, a long filament of coated fiber is wound on a spool in such a way that the maximum arrangement of fiber density is achieved For example, the spool may have a cross section exhibiting a hexagonal close-packed arrangement of the fibers. In another embodiment, a plurality of fibers may be grown or formed into a particular arrangement prior to coating. Once coated and arranged, the fiber mass is compressed and constrained so that shapes can be cut out in various thicknesses, such as, for example, approximately 50 microns to 5000 microns. Each sheet is sintered to bind the metal and remove the fiber, leaving a porous anode that can be oxidized and formed in the usual manner for a capacitor.
