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 is directed to a high voltage, highly conductive electrolyte for use in 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 N-methylformamide; a combination of hypophosphorous acid, boric acid and an aliphatic dicarboxylic acid of carbon chain length from eight to twelve, such as azelaic, sebacic, or brassylic acid; an amine including ammonia, ammonium hydroxide, diethylamine, dimethylamine, triethylamine, or triethanolamine; and a nitro-substituted aromatic compound as a degassing agent, such as 3′-nitroacetophenone. Anhydrous ammonia may also be added to neutralize the solution. In an alternative embodiment of the electrolyte of the present invention, the ethylene glycol/NMF two solvent mixture can be substituted with 1,2-propanediol, using &ggr;-butyrolactone as a cosolvent with or without NMF. The electrolyte of the present invention will allow the construction of multi-anode capacitors with low equivalent series resistance (ESR), which will have superior energy density and delivery, while being thinner due to fewer spacer and cathode layers with the same number of anodes. This resultant capacitor, when incorporated into an ICD, will reduce the size and thickness of the overall device.

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 di(ethylene glycol); a combination of boric acid with an aliphatic dicarboxylic acid of carbon chain length from eight to thirteen, such as suberic, azelaic, sebacic, undecanedioic, dodecanedioic, or brassylic acid; a very long chain dicarboxylic acid, where the acid moieties are separated by 34 carbons; and a nitro-substituted aromatic compound as a degassing agent, such as 3-nitroacetophenone or 2-nitroanisole. This electrolyte is then titrated with a light amine such as ammonia, diethylamine, dimethylamine, trimethylamine, or triethylamine. The electrolyte according to the present invention, when impregnated in an electrolytic capacitor, provides an acceptable breakdown voltage while having a reasonable bulk conductivity. This electrolyte, when impregnated within a capacitor constructed of appropriate foils and paper spacers, should provide a part with a working voltage of at least 500 volts, while having a bulk conductivity of approximately 3 mS/cm.
