Embodiment Construction

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0027] A new type of electrolytic paper has a honeycomb network structure, the honeycomb network structure is filled with solutes, and the solutes can be dissolved in the electrolyte, so that the viscosity of the electrolyte can be increased and the performance of the electrolyte can be improved. At the same time, the performance of the capacitor is also improved. This is improved because by the time the solute is released slowly, the capacitor assembly has bee...

Abstract

The invention provides novel electrolytic paper, a manufacturing method thereof, an electrolytic capacitor and a manufacturing method thereof. The electrolytic capacitor comprises a core package, wherein the core package comprises the novel electrolytic paper, the novel electrolytic paper has a cellular network structure, the cellular network structure is filled with a solute, and the solute can be dissolved in an electrolyte. Compared with the prior art, the novel electrolytic paper, the manufacturing method thereof, the electrolytic capacitor and the manufacturing method thereof solve a problem of poor impregnation effect through reducing the viscosity of the electrolytic and performing ultrasonic vibration impregnation. Meanwhile, a trace of solute used for adjusting the viscosity of the electrolytic and an additive are adsorbed on the electrolytic paper, the adsorbed solute is slowly released in the subsequent high-temperature aging and application after a capacitor product is assembled so as to improve the viscosity of the electrolytic and improve the sparking voltage and the safety performance.

Description

technical field [0001] The invention relates to the technical field of preparation of electrolytic capacitors, in particular, to a novel electrolytic paper and a manufacturing method thereof, and an electrolytic capacitor and a manufacturing method thereof. Background technique [0002] The aluminum electrolytic capacitor in the related art is composed of four layers of anode aluminum foil, first electrolytic paper, cathode aluminum foil, and second electrolytic paper. It is prepared after refining and testing steps. [0003] In order to increase the capacity of the capacitor, more aluminum foil needs to be wound in a limited space, so the winding of the core package in the related art is generally relatively compact. As a result, when the core bag is impregnated with electrolyte, it will be difficult to completely impregnate it. Therefore, in order to make the core pack better impregnated with the electrolyte, the viscosity adjustment is generally paid attention to when p...
