US 2026/0279689 A1 · FABRICATION OF CAPACITORS

Abstract

The capacitor has an electrode stack with faces between one or more edges. A bent portion of the one or more edges has a bend in the one or more edges. An adhesive film is positioned on the electrode stack such that an edge region of the adhesive film is over the bent portion of the one or more edges. The adhesive film includes multiple flaps. The multiple flaps include a first flap connected to a first portion of the edge region and a second flap connected to a second portion of the edge region. The first flap and the second flap are positioned over a first one of the faces of the electrode stack. A lateral edge of the first flap intersects a lateral edge of the second flap at a common location.

Dependent claims

An electrolytic capacitor, comprising:

a cathode that includes a porous material on a cathode metal, a face of the cathode metal including a shelf that is not under the porous material, the shelf extending out from under the porous material to an edge of the cathode metal;
an electrode stack having faces between one or more edges, a bent portion of the one or more edges having a bend in the one or more edges, wherein the cathode is included in the electrode stack;
and
an adhesive film being positioned on the electrode stack such that the adhesive film is positioned over the bent portion of the one or more edges.
