Abstract

The invention discloses a high specific volume electrolytic capacitor roll core isolation assembling method; a dipped roll core is isolated from a fixing liquid, and a specific method is to wrap a capacitor paper layer outside the dipped roll core, so black glue and the capacitor roll core can be isolated in the fixing liquid, and copper, iron, chloride ion and impurity in the black glue cannot dip into an anode and a cathode of the capacitor roll core, thus preventing conduction and reaction under high temperature, hydrogen cannot be generated, so blast phenomenon can be eradicated. The capacitor paper is low in tightness, high in intensity, small and uniform in hole diameter, has small accident loss probability in usage, and capacitor internal resistance is not added; the leakage current is small, energy storage effect is good, and capacitor production can be convenient.

Description

technical field [0001] The invention belongs to the industry of electronic components, and in particular relates to a winding core isolation assembly method of a high specific capacitance electrolytic capacitor. Background technique [0002] Electrolytic capacitors have electrolyte materials that store charges inside, which are divided into positive and negative polarities, similar to batteries, and cannot be reversed. The positive electrode is a metal substrate with an oxide film, and the negative electrode is connected to the electrolyte (solid and non-solid) through a metal plate. [0003] Nonpolar (bipolar) electrolytic capacitors adopt a double oxide film structure, which is similar to two polarized electrolytic capacitors formed by connecting two negative electrodes, and the two electrodes are two metal plates (both with oxide films) The two groups of oxide films are connected with electrolyte in the middle. Polar electrolytic capacitors are usually used in power cir...
