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.

摘要： The present invention is directed to a method of etching anode foil in a non-uniform manner which increases the overall capacitance gain of the foil while retaining foil strength. In particular, by using a mask to protect a mesh grid of the foil from further etching, a previously etched foil can be further etched, prior to the widening step. Alternatively, the mask may be used in the initial etch, eliminating the need for the second process. In effect the foil may be etched to a higher degree in select regions, leaving a web of more lightly etched foil defined by the mask to retain strength. According to the present invention, the foil is placed between two masks with a grid of openings which expose the foil in these areas to the etching solution. The exposed area can be as little as 10% of the total foil to as much as 95% of the total foil, preferably 30% to 70% of the total foil area. The pattern is configured in such a way that the enhanced area does not create large scale strength defects such as perforation holes and is held in a pattern such as a hexagonal array, random array or radial burst array, such that the exposed area perimeter can be round, square, hexagonal, or triangular. The higher surface area in the exposed areas does not significantly decrease the strength of the foil as a whole, such that the method according to the present invention increases capacitance of the anode foil without significantly decreasing the strength of the foil.

摘要： The present invention is directed to a method of encasing electrolytic capacitor stacks or wound rolls to form an external package. First, a plastic sheet is heated to its soft transition temperature. Next, the plastic sheet is draped over a preassembled capacitor stack or wound roll. Then, a vacuum is applied to the capacitor stack or wound roll, such that the sheet is formed around the stack or wound roll. Finally, the plastic sheet is allowed to cool. This process results in a vacuum formed plastic capacitor case assembly which minimizes wasted volume in the capacitor package and minimizes capacitor assembly time.

摘要： The present invention is directed to a method of creating porous anode foil for use in multiple anode stack configuration electrolytic capacitors, producing a pore structure that is microscopic in pore diameter and spacing, allowing for increased energy density with a minimal increase in ESR. Initially, an anode metal foil is etched, according to a conventional etch process, to produce an enlargement of surface area. The etched foil is then placed into the electrochemical drilling solution of the present invention. Alternatively, the etched foil may be masked, so that only small areas of the etched foil are exposed, prior to being placed in the electrochemical drilling solution. A DC power supply is used to electrochemically etch the masked or unmasked foil in the electrochemical drilling solution of the present invention such that pores on the order of a few microns diameter are produced through the foil. The electrochemical drilling solution of the present invention consists of 1 to 15% by weight sodium chloride, preferably 5% by weight, and 10 to 5000 PPM of a surface passivator, such as sodium nitrate or phosphoric acid, preferably 500 PPM. Finally, the foil pores are widened and the foil is formed to the intended use voltage according to conventional widening and forming processes. When used in conjunction with an electrochemical etch preceding it and an electrochemical widening step following it, the electrochemical drilling step of the present invention results in an electrically porous foil which maintains the high capacitance gain produced by the etching and widening steps alone, but, when used in a multiple anode stack configuration, exhibits a reduced equivalent series resistance.
