    摘要： A method of producing a highly etched electrode for a capacitor from a foil is disclosed. The method comprises first applying a laser beam to the foil to form a plurality of marks on the foil surface and then etching the foil. Preferably, the laser marks facilitate etching of foil surface in areas near the marks and retard etching of foil surface inside the marks. After etching, the foil is further processed in a combination of optional steps such as forming and finishing steps. The laser marking of the foil allows for positional control of tunnel initiation, such that tunnel initiation density and the location of tunnel initiation is controlled. By controlling the position of tunnel initiation, foils are etched more uniformly and have optimum tunnel distributions, thus allows for the production of highly etched foils that maintain high strength and have high capacitance. The present invention further includes an electrolytic capacitor comprising etched aluminum anode foils, which have been prepared using the methods of the present invention.

    摘要翻译： 公开了一种从箔制造用于电容器的高蚀刻电极的方法。 该方法包括首先将激光束施加到箔上以在箔表面上形成多个标记，然后蚀刻箔。 优选地，激光标记便于在标记附近的区域中蚀刻箔表面并延迟对标记内的箔表面的蚀刻。 在蚀刻之后，箔可以以可选步骤的组合进一步加工，例如成型和精加工步骤。 箔的激光标记允许隧道起始的位置控制，使得隧道起始密度和隧道起始的位置被控制。 通过控制隧道起始的位置，箔被更均匀地蚀刻并且具有最佳的隧道分布，从而允许生产保持高强度并具有高电容的高度蚀刻的箔。 本发明还包括使用本发明的方法制备的包含蚀刻的铝阳极箔的电解电容器。

    摘要： 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.

    摘要： Anode foils suitable for use in electrolytic capacitors, including those having multiple anode configurations, have improved strength, reduced brittleness, and increased capacitance compared to conventional anode foils for electrolytic capacitors. Exemplary methods of manufacturing an anode foil suitable for use in an electrolytic capacitor include disposing a resist material in a predetermined pattern on an exposed surface of an anode foil substrate such that a first portion of the exposed surface of the anode foil substrate is covered by the resist material, and a second portion of the exposed surface remains uncovered; polymerizing the resist material; exposing at least the second portion of the exposed surface to one or more etchants so as to form a plurality of tunnels; stripping the polymerized resist material; and widening at least a portion of the plurality of tunnels. The resist material may be deposited, for example, by ink-jet printing, stamping or screen printing.
