Abstract

The present invention is directed toward an enhanced very high volt electrolyte for use in electrolytic capacitors. In particular, by the inclusion of a polymer matrix of a hydrogel, preferably of the family of poly(hydroxy alkyl methacrylate) but also including polyvinylalcohol (PVA), polyacrylonitrile (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. An electrolytic capacitor impregnated with the enhanced very high volt electrolyte of the present invention, is capable of operating at a voltage of 700 to 800 volts. 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.
