摘要： A conductive electrolyte comprises an indicator dye for facilitating detection of electrolyte leakage in a high voltage electrolytic capacitor as well as for facilitating the determination as to when an electrolyte has reached a desired pH range. In a method for detecting electrolyte leakage, a capacitor comprising a flat stack of anodes enclosed in a housing with a lid and an electrolyte comprising an indicator dye is inspected for the presence of electrolyte leaking out of the capacitor. The indicator dye facilitates viewing leaking electrolyte. The indicator dye can be a coloring agent that changes the color of the electrolyte or can be a fluorescent that fluoresces when exposed to ultraviolet light. The indicator dye is also utilized as a pH indicator during the manufacture of electrolytic capacitors, wherein a base is introduced into an electrolyte having an indicator dye that changes pH when the electrolyte turns basic. The base is introduced into the electrolyte until the indicator dye causes the electrolyte to change color indicating the desired pH has been reached.

摘要： The present invention is directed to a conductive electrolyte for use in high voltage electrolytic capacitors and to an electrolytic capacitor impregnated with the electrolyte of the present invention for use in an implantable cardioverter defibrillator (ICD). The electrolyte according to the present invention is composed of a two solvent mixture of ethylene glycol and a polar organic cosolvent from the group of 2-methoxyethanol, 2-ethoxyethanol, 2-butoxyethanol, hexyl alcohol, or di(ethylene glycol). Dissolved in this mixture is a combination of boric acid with either an aliphatic dicarboxylic acid of carbon chain length from eight to thirteen (C8 to C13) or a very long chain dicarboxylic acid, where the acid functional groups are separated by 34 carbons (referred to as “dimer acid”). The solution is then neutralized with an amine. A cathode depolarizer, or degassing agent, from the group of nitro-substituted aromatic compounds (nitroaromatics) can be added to reduce the amount of gas produced during capacitor life. Hypophosphorous acid and/or a colloidal suspension of silica in ethylene glycol may be added to enhance the life characteristics of the electrolyte, resulting in lower leakage currents and better voltage droop characteristics. The water content may be adjusted with deionized water to achieve a Karl Fischer titration (water content) measurement of 1.0-8.0% to achieve proper age characteristics.

摘要： The present invention relates to an improved method of impregnating electrolytic capacitor stacks or wound rolls with a polymer based electrolyte, such as a hydroxyethylmethacrylate (HEMA) or hydroxyethylacrylate (HEA) based electrolyte, to render them suitable for use in electrolytic capacitors, and to such electrolytic capacitors. The initiator to promote the polymerization of the polymer based electrolyte and a surface active wetting agent are deposited on the foil or in the stack or wound roll prior to impregnation of the stack or wound roll with a polymer based electrolyte, allowing the polymer based electrolyte solution to be warmed prior to impregnation to a temperature suitable for easy impregnation into the anode and cathode foil and paper. Polymerization does not begin until impregnation of the capacitor with the polymer based electrolyte and the surfactant allows the polymer based electrolyte to more fully incorporate itself into the microscopic features of the anode foil.

摘要： The present invention is directed toward a very high volt capacitor for use in an implantable cardioverter defibrillator. In particular, by the inclusion of a polymer matrix of a hydrogel, preferably of the family of poly(hydroxyalkylmethacrylate)but also including polyvinyl alcohol (PVA), polyacrylnitrile (PAN), into a standard fill electrolyte, the breakdown voltage of the enhanced very high volt electrolyte of the present invention is raised to as much as 800 V. A very high volt electrolytic capacitor according to the present invention, impregnated with the enhanced very high volt electrolyte of the present invention, is able to support voltages of 700 to 800 volts, while maintaining the described desired properties, and is therefore superior to other known electrolytic capacitors for use in implantable cardioverter defibrillators. The production of a very high volt capacitor capable of operating at a voltage of 700 to 800 volts allows a single high volt electrolytic capacitor to replace the conventional two capacitors-in-series arrangement of an Implantable Cardioverter Defibrillator (ICD). Having a single high voltage capacitor results in savings in cost and in space required, especially where internal volume is at a premium, such as in an ICD and related medical implant devices.

摘要： An anode foil treatment method produces a useful high quality oxide with inherently high capacitance at voltages as high as 750 Volts or more. The anode foil treatment method comprises a series of formation and relaxation steps. Oxide layer formation is performed in a forming mixture that includes a high molecular weight dicarboxylic acid that is made into a salt and a strong base. The concentration of the dicarboxylic acid is carefully monitored and kept within a narrow band. The complex by-product of the dicarboxylic salt created during formation process is kept below a fixed maximum level.
