Abstract
The present invention is directed to a gelled electrolyte and to an electrolytic capacitor impregnated with the gelled electrolyte of the present invention for use in an implantable cardioverter defibrillator (ICD). The electrolyte gel according to the present invention is generated by the addition of a gelling agent, preferably D-mannitol, to a conventional electrolyte. The gelling agent of the present invention can be used in ethylene glycol based electrolyte systems with or without a polar organic cosolvent. Dissolved in this mixture is an aliphatic dicarboxylic acid of carbon chain length from eight to thirteen (C to C ) as the ionogen. In order to achieve the necessary electrolyte conductivity, an amine is added to adjust the electrolyte pH to within a range of 6-10. An amount of D-mannitol is added to the electrolyte to reach the final weight percent of 8-15% by weight of the total electrolyte mixture.
