摘要： A process for creating an anode foil for use in an electrolytic capacitor of an implantable cardioverter defibrillator is provided. The process includes placing a partially masked bulk metal foil in an etch electrolyte solution to etch exposed area of the bulk metal foil, removing the etch-resistant mask to expose the unetched areas, widening the bulk metal foil, and partially cutting the bulk metal foil between a plurality of unetched areas to form a partially detached etched foil anode, such that the unetched areas are not cut and the unetched areas serve as attachment tabs to keep the partially detached etched foil anode attached to the bulk metal foil. Additionally, the process may include an oxide formation step, wherein the step of partially cutting the bulk metal foil is performed after the etching and widening steps, and before the oxide formation step.

摘要： A capacitor includes an anode foil, a cathode foil, a conductive electrolyte, and a separator between the cathode foil and the anode foil. The conductive electrolyte fills between the cathode foil and the anode foil and contains butyrolactone. The separator includes an aromatic polyamide fiber material. The aromatic polyamide fiber material is non-woven and includes a para-aromatic-polyamide synthetic fiber. The separator has a thickness in a range of about 5 μm to about 20 μm and a density of greater than about 1.0 g/cm3.

摘要： An electrolytic capacitor is disclosed having a housing in an arced-trapezoidal shape. Disposed within the housing are one or more anodes, one or more cathodes, one or more separators disposed between anodes that are adjacent anodes cathodes, and an electrolyte disposed around the one or more anodes, the one or more cathodes, and the one or more separators within the housing. The housing of the electrolytic capacitor includes front and back walls shaped as arced-trapezoids and four sidewalls that substantially follow the outline of the front and back walls. The electrolytic capacitor is configured to connect in series with one or more electrolytic capacitors of the same shape to form a capacitor assembly. In the capacitor assembly, electrolytic capacitors are placed such that sidewalls are adjacent to each other to form a D-shaped capacitor assembly.
