A solid electrolytic capacitor element includes an anode body, a dielectric layer disposed on a surface of the anode body, a solid electrolyte layer covering at least a part of the dielectric layer, and a cathode lead-out layer covering at least a part of the solid electrolyte layer. The cathode lead-out layer includes a carbon layer that is in contact with the solid electrolyte layer and covers at least a part of the solid electrolyte layer. The carbon layer includes a carbonaceous material and a cyclodextrin compound. The cyclodextrin compound has a concentration of a saturated aqueous solution at 25° C. of 1.5 mass% or more.

Fabricating a capacitor includes performing an oxide formation operation on a sheet of material. The oxide formation operation forms an anode metal oxide on an anode metal. A thermal compression is performed on the sheet of material after the oxide formation operation is performed. The thermal compression applies thermal energy to the sheet of material while applying pressure to the sheet of material. After the thermal compression, the capacitor is assembled such that at least one electrode in the capacitor includes at least a portion of the sheet of material.

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.

An electronic substrate or interposer comprising nanoporous films, such as anodic aluminum oxide, containing vertically etched openings (“vias”) that are filled with a conductive material, forming a high density collection of vertically oriented vias that conduct electricity from one side of the substrate to the other.

The instant disclosure relates to a method for making solid electrolytic capacitor package structure with improved conductive terminals. The first step is to provide at least one conductive terminal having an electrical contact portion and a lead-out portion. The next step is to remove a portion of mantle layer from the surface of the core layer of at least one conductive terminal by a dry-type process. The next step is to sequentially stack together a plurality of stacked-type capacitors to form a capacitor unit and then electrically connect the capacitor unit to at least one conductive terminal. The next step is to form a package body to encapsulate the capacitor unit and the electrical contact portion of at least one conductive terminal. The last step is to bend the lead-out portion of at least one conductive terminal to an axis that extends along the surface of the package body.
