    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： A method of producing an electrode for use in the manufacture of electrolytic capacitors for implantable cardioverter defibrillators comprises first coating the foil with a photoresist, second, applying a holographic image to the photoresist, third, removing a portion of the photoresist to expose a portion of the foil and create a pattern of photoresist on the foil and etching the foil. Alternatively, the method comprises applying an oxide or metal layer to the exposed foil surface, removing the pattern of photoresist to create a pattern of oxide or metal and etching the foil. The patterns of photoresist, oxide or metal all retard or prevent etching of the foil where the foil surface is covered. This results in a pattern of unetched foil with the remaining area being heavily etched. The resulting patterns stop crack propagation through the etched portions to yield foils with high gain and improved strength.
