Problems solved by technology

The connection method in the related technology is: the connection between the monomers is vertically superimposed, such as figure 1 As shown, two or more capacitors (such as capacitor 1 and capacitor 2) are glued together after the single capacitor is manufactured to obtain a combined supercapacitor, but the thickness of the corresponding capacitor will increase exponentially. Especially in devices with high vertical requirements, supercapacitors cannot provide applications, especially under the condition of small thickness space, the disadvantages are more obvious
In addition, after two or more capacitors form a supercapacitor, it is necessary to perform tab welding on the outside of each capacitor of the supercapacitor, which increases the process flow and is very cumbersome to operate

Abstract

The invention discloses a super capacitor comprising a capacitor body, two outside-of-group tabs and an outer package, wherein the capacitor body is provided with a first end and a second end and comprises a plurality of single-cell capacitors, the plurality of single-cell capacitors are connected in series and / or in parallel, the first end is connected with a first single-cell capacitor in the plurality of single-cell capacitors, the second end is connected with a last single-cell capacitor in the plurality of single-cell capacitors, one of the two outside-of-group tabs is connected with the first end while the other of the outside-of-group tabs is connected with the second end, and the outer package is used for packaging the capacitor body. The super capacitor can be used for effectively reducing device thickness and packaging steps, and the super capacitor is simple in structure and easy to implement.

Description

technical field [0001] The invention relates to the technical field of energy storage devices, in particular to a supercapacitor. Background technique [0002] A supercapacitor is a new type of energy storage device between a physical capacitor and a secondary battery. This new type of energy storage device is unique in its energy storage and release process, which is not only reflected in the high pulse rate charge and discharge process, but also has the advantages of high energy and high specific power, that is, the charge and discharge time is only tens of seconds, and its Compared with batteries, the power density is 10 to 100 times higher; the energy density is 100 times that of physical capacitors. At present, most of the energy storage devices used in low-power devices such as microelectronic circuits are supercapacitors, which have high requirements for power density and energy density. How to make full use of the energy storage of supercapacitors in a limited space...
