Problems solved by technology

Because during the impregnation process of the monomer and the oxidant, the oxidant and the monomer will climb to the junction of the round rod part and the flat part, and form a conductive path after polymerization, which will increase the leakage current

Abstract

A method for producing a solid aluminum electrolytic capacitor in use of asymmetric electrolytic paper core cladding comprises the steps: clamping electrolytic paper between two guide pins, wherein the electrolytic paper is wider than an electrode foil; two parts, exceeding the electrode foil, at two edges coiled with the electrolytic paper are not the same; the part, exceeding the foil, at one end close to a CP line is more than the other part; and the exceeding part arrives at the joint of the round bars of the guide pins and a flat plate; covering the joint of the round bars of the guide pins and the flat plate in use of the electrolytic paper; and then obtaining the solid aluminum electrolytic capacitor after conventional carbonization, impregnation and polymerization. In the produced solid aluminum electrolytic capacitor, the electrolytic paper covers the junction of the round bars of the guide pins and the flat plate; during the formation of the core cladding, becuase the electrolytic paper is fully absorbed with the electrolyte, the electrolytic paper is clung to the round bars and the flat plate, the gas absorption is damaged and the gas separation to the formed liquid and an aluminum body is avoided or weakened; the junction of the round bars and the flat plate is formed better and the pellumina layer on the surface is covered better.

Description

technical field [0001] The invention relates to the technical field of preparation of electrolytic capacitors, in particular to a method for manufacturing solid electrolyte aluminum electrolytic capacitors. Background technique [0002] The replacement products of traditional liquid capacitors for solid capacitor operation have their own unique and excellent characteristics, and the existing common liquid capacitor winding method is also used in structure, that is, the positive electrode foil and the negative electrode foil are respectively riveted with guide pins, and the two layers of foil There are two sheets of electrolytic paper between them. The width of the electrolytic paper is wider than that of the two electrode foils, so as to ensure that the two electrode foils will not touch during the coiling, production and use process, forming a short circuit of the product. The existing technology is that the part of the electrolytic paper that exceeds the electrode foil is ...
