Abstract

The invention discloses a large-capacity electrochemical device individual structure. The structure comprises aluminum polar columns, an aluminum pot, cover plates, current collectors and an electrode roll core, wherein each of two end surfaces of the electrode roll core is connected with the current collector; the two current collectors are connected with the aluminum polar columns at two ends respectively; the aluminum polar columns are stepped columns; the cover plates sleeve the aluminum polar columns; an insulated ring is arranged between the end surface of one side of each cover plate and each aluminum polar column; a seal ring is arranged between the inner ring wall of each insulated ring and each aluminum polar column; the seal rings are pressed on the aluminum polar columns through plastic fixing blocks; the inner ring walls of the cover plates are isolated from the aluminum polar columns through the insulated rings and the plastic fixing blocks; and clamp springs are arranged at the upper parts of the plastic fixing blocks to perform locating. The invention furthermore discloses a large-capacity electrochemical device individual structure-based large-capacity electrochemical device individual assembling method. By adopting the structure and the method, the production process is simple; automated production is easy to realize; the product uniformity is improved; the production cost is reduced; the use of super capacitors in all industries is facilitated; and the aluminum pot is electrically neutral, so that the reliability is improved.

Description

technical field [0001] The invention belongs to the technical field of electrochemical energy storage devices, and in particular relates to a single structure of a cylindrical large-capacity electrochemical device that is easy to realize automatic processing, safe and reliable, and an automatic assembly method thereof. Background technique [0002] Supercapacitor is a new type of energy storage device between traditional capacitors and rechargeable batteries. Its capacity can reach several thousand farads. Compared with traditional capacitors, it has larger capacity, higher energy, and wider working temperature and extremely long service life, and compared with batteries, it has higher specific power and no pollution to the environment. It has a wide range of national strategic emerging industries including rail transit, wind power generation, public buses, and smart grids. Market demand, but due to the structure of traditional supercapacitors, the current collectors are usu...
