Capacitor liquid coating device and capacitor preparation method

Abstract

The invention provides a capacitor liquid coating device and a capacitor preparation method, and relates to the technical field of liquid coating devices. The capacitor liquid coating device comprises a containing box, electrolyte is contained in the containing box, a winding assembly is connected with the containing box, and the winding assembly comprises a driving part fixed to the outer side of the containing box and a winding part rotationally connected to the interior of the containing box; the rotating end of the driving part drives the winding part to rotate in the accommodating box, the winding part is used for winding electrolytic paper and positive and negative electrode aluminum foils into elements, and the electrolytic paper can be in contact with electrolyte, so that the electrolytic paper is always impregnated in the electrolyte from the beginning of element manufacturing to the completion of element manufacturing; and the electrolyte and the winding assembly are arranged in the accommodating box, and the electrolytic paper is always soaked in the electrolyte from the beginning of element manufacturing to the completion of element manufacturing, so that the electrolytic paper can fully absorb the electrolyte, the quality of the element is improved, and the electrolytic paper coated with the electrolyte is prevented from being transported again.

Description

technical field [0001] The invention relates to the technical field of liquid coating devices, in particular to a capacitor liquid coating device and a capacitor preparation method. Background technique [0002] Capacitor is a new type of energy storage element similar to battery. Its power density is dozens of times higher than that of battery. It has the advantages of fast charging and discharging, no pollution to the environment, and long cycle life. One of green energy. The part inside the capacitor used to store electrical energy is called a prime, which consists of 2 to 4 layers of electrolytic paper, positive and negative aluminum foils, positive and negative lead wires, and termination tape. [0003] In the prior art, such as the authorized announcement number: CN111341563B, the disclosed capacitor liquid coating device and capacitor preparation method include a capacitor liquid coating device, the capacitor liquid coating device includes a liquid coating structure ...

AI Technical Summary

Problems solved by technology

[0005] There are problems in the existing technology: 1. After the electrolytic paper is wound, the end of the formed element needs to be impregnated in the electrolyte again to fully infiltrate the end of the formed element, and the production process is not simplified; 2. When the electrolytic paper is coated by roller coating, the excess filtered electrolyte needs to be recovered, and the related electrolyte recovery mechanism increases the manufacturing cost of the liquid coating device; 3. The electrolyte is transported to the liquid coating component 4. Apply electrolyte to the unfolded electrolytic paper before winding, and the coated electrolytic paper needs to be transported to At the winding place, the element is made. During this process, the coated and unfolded electrolytic paper is fully in contact with the outside air, which will increase the evaporation of the electrolyte, affect the quality of the element, and pollute the working environment.
