Abstract: A method for preparing a stacked solid aluminum electrolytic capacitor is disclosed. The method includes preparation of a plurality of cores, stacking and fixing of the plurality of cores in a case and encapsulation of the case. The core is prepared through the following steps. An I-shaped aluminum foil is divided into an anode part and a cathode part by applying an insulating blocking tape, where the cathode part includes a dielectric layer, which is subjected to formation. A conductive polymer layer is formed on a surface of the cathode part, and is then impregnated with conductive colloidal graphite followed by drying to form a conductive carbon paste layer. The conductive carbon paste layer is impregnated with a conductive silver paste followed by drying to form a conductive silver paste layer. After that, a core is obtained.

Abstract: This application provides a multilayer solid aluminum electrolytic capacitor and a method for preparing the same. The multilayer solid aluminum electrolytic capacitor includes a plurality of cores, a rivet, a case, and a cover plate. The cores are stacked in sequence and fastened in the case through the rivet to form a semi-finished capacitor. The semi-finished capacitor is covered by the cover plate and then sealed to form the solid aluminum electrolytic capacitor.
