摘要： 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.
