Supercapacitor module

Abstract

The invention discloses a supercapacitor module which comprises at least two capacitor individuals and at least one connecting piece used for connecting the capacitor individuals. Each capacitor individual comprises a first barrel, a second barrel and an electrode core, each first barrel and the corresponding second barrel are hermetically connected through a sealing ring, each electrode core is arranged in a sealing cavity formed by the corresponding first barrel and the corresponding second barrel which are different in weight, and each capacitor individual is in a mode where the barrel large in weight is positioned at the bottom of the barrel small in weight. Each capacitor individual is in a mode that the barrel large in weight is positioned at the bottom of the barrel small in weight, so that vibration amplitude of the sealing rings due to stress is lowered greatly; working reliability of the supercapacitor module is guaranteed, and service life of the supercapacitor module is prolonged.

Description

technical field [0001] The invention relates to an energy storage device, in particular to a supercapacitor module. Background technique [0002] When traditional supercapacitor manufacturers produce supercapacitor modules, they define the outer shell as the positive pole and the upper cover as the negative pole or the outer shell as the negative pole and the upper cover as the positive pole. When assembling the supercapacitor into a module, They are all assembled in series, that is, the positive terminal (housing or upper cover) of one monomer is connected in series to the negative terminal (upper cover or housing) of another monomer, that is to say, no matter how the supercapacitor defines the positive and negative poles, in When assembling the module, both the shell and the upper cover will face down at the same time. [0003] see figure 1 as shown, figure 1 is a schematic diagram of the assembly of a conventional supercapacitor module. The supercapacitor module with ...

AI Technical Summary

Problems solved by technology

The supercapacitor module with this structure has the following disadvantages: after the electrodes are put into the shell, the weight of the electrode roll itself is pressed on the bottom of the shell, and the bottom of the shell is integrated with the appearance, and the strength is enough to support the weight of the electrode roll

There is a sealing ring between the upper cover and the outer casing. The sealing ring is made of rubber and is a flexible structure. If the upper cover is lowered, the weight of the electrode roll itself will press on the upper cover, and the upper cover is passed on the upper cover. A sealing ring is added between the cover and the shell to be fixed by the extrusion force of the sealing ring, and the sealing ring is a flexible material. If there is vibration, the sealing ring will move up and down with the vibration, which will cause the electrode coil to be damaged. Continuously moving up and down with the vibration, the welding at both ends of the electrode roll is pulled apart, causing the supercapacitor to lose performance
