Solid electrolytic capacitor and method of processing the same

Abstract

The invention provides a solid electrolysis capacitor with small impedance, large electric capacity, stronger thermal endurance and weathering resistance. The product may not be broken because of transportation for high yield and strong capability for bearing external force of the product. Thus, the invention further provides a process method of capacitors, comprising: an anode film, an anode, a cathode film, a cathode and a conductivity high polymer electrolyte layer between the anode film and the cathode film. Surface of the anode film covers an oxidation electric surface layer. Carrier of the conductivity high polymer electrolyte layer is a separation layer, characterized in that the separation layer is a film containing carbon fibres. Process method of capacitors comprises steps of: regarding etched conduction metal foil as the anode film, of which the surface is treated with anode oxidation to form the oxidation electric surface layer, the anode film leading a lead form an anode; manufacturing the cathode film by using the metal foil and leading the lead to form a cathode; winding the anode film, the cathode film and the separation layer between them into a cylinder shape to complete subassemblies of the capacitor; finally, packing subassemblies of the capacitor into a box, or covering with a protection layer to obtain the solid electrolysis capacitor.

Description

(1) Technical field [0001] The invention relates to a capacitor, in particular to a solid electrolytic capacitor and a processing method thereof. (2) Background technology [0002] As we all know, the basic function of a capacitor is charging and discharging. This basic charging and discharging function generates many circuit phenomena, so that capacitors can be used in many different occasions. For example, in electric motors, capacitors can be used to generate phase shifts. In photographic flashlights, capacitors can be used to generate instantaneous discharge of energy; and in electronic circuits, capacitors also have many different uses. For example, bypass capacitors can actually be used as smoothing filter capacitors and rectifiers. However, capacitors are so many For different purposes, the basic function of charging and discharging is the same. [0003] Capacitors can be roughly divided into electrolytic capacitors and non-electrolytic capacitors according to their ...

AI Technical Summary

Problems solved by technology

Because the release paper itself is a non-conductive material, although it has better adsorption capacity, it has the disadvantages of high impedance, poor heat resistance, weather resistance, etc., which shortens the life of electrolytic capacitors.

Although the separator paper is carbonized to reduce the insulation resistance of the separator and prolong the life of the electrolytic capacitor, however, the carbonization of the separator paper becomes extremely fragile and the structure is unstable, and it is difficult to withstand external forces, which leads to poor stability of the electrolytic capacitor during manufacture. leading to low yield

On the other hand, because the structure of the carbonized thermal insulation paper is loose and unstable, it is easy to cause the capacitor to be damaged by external force during the transportation process, which will affect its electrical characteristics and affect the electronic circuit.
