International Classification:

H01G 9035
US Classification:

252 622, 361506, 361504, 607 5, 429326, 429339, 429341, 429343
Abstract:

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.

US Patent:

6587329, Jul 1, 2003
Filed:

May 23, 2002
Appl. No.:

10/154569
Inventors:

Christopher Feger - Easley SC
Assignee:

Pacesetter, Inc. - Sunnyvale CA
International Classification:

H01M 604
US Classification:

361504, 361508, 361503, 361523, 361528, 252 622
Abstract:

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 an alkoxy-substituted alcohol, such as 2-methoxyethanol, 2-ethoxyethanol, or 2-butoxyethanol. Dissolved in this mixture is a combination of acids including at least one straight chain aliphatic dicarboxylic acid of carbon chain length from eight to thirteen (C to C ) and a longer chain dicarboxylic acid, where the acid functional groups are separated by 34 carbons (referred to as âdimer acidâ). As further additives, boric acid and hypophosphorous acid can be added, with the former providing corrosion inhibition in the finished capacitor, and the latter resulting in lower leakage currents and better voltage droop characteristics. Also, 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.

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 -butyrolactone as a cosolvent with or without NMF.

Inventors:

Naixiong Jiang - Palo Alto CA, US
Timothy Marshall - Pickens SC, US
Melissa Moore - Greenville SC, US
Christopher R. Feger - Easley SC, US
Thomas F. Strange - Easley SC, US
Assignee:

International Classification:

C25D 9/02
C25D 5/44
US Classification:

205317, 205212, 205213, 205214
Abstract:

The present invention is directed to a conductive polyethylenedioxythiophene (PEDOT) polymer coated electrode adapted for use as a cathode electrode of an electrolytic capacitor and a method of manufacturing the same. According to the present invention, a metal foil substrate is placed in an aqueous solution of a doped 3,4-ethylenedioxythiophene (EDOT) monomer and a co-solvent, to dissolve the EDOT monomer, and a current is applied until the desired thickness of the polymer coating is electrochemically deposited. Additionally, an organic acid is added to the aqueous solution to act as an oxidizer. In order to improve the uniformity and adherence of the coating a surfactant may also be added. In a preferred embodiment, the EDOT monomer and cosolvent are first mixed, and then added to a water solution of oxidizer and dopant. The polymer film is deposited electrochemically onto the substrate by applying a DC current between 0.
