Embodiment Construction

[0031] The present invention proposes a flexible packaging method for supercapacitors with a laminated structure, which will be described below with reference to the accompanying drawings.

[0032] The flexible packaging method of the supercapacitor with a stacked structure includes a single package and a multi-cell series package;

[0033] Such as figure 1 The single package shown includes the use of elastic flange structure to ensure that the electrodes are easily deformed under pressure; the liquid is injected through the pinhole to ensure the internal vacuum environment and prevent the stability of the package from being damaged due to long-term slow gas production; Sealing to further ensure the reliability of the device packaging structure; the specific steps are as follows:

[0034] (1) The current collector, elastic positive electrode, separator, elastic negative electrode and current collector are obtained by cutting with a slicer; the length and width of the elastic ...

Abstract

The invention discloses a flexible packaging method for supercapacitors with a laminated structure, which belongs to the technical field of supercapacitor preparation. Including single-unit packaging and multi-unit series packaging; specific steps: building a stacked structure and placing it; flange structure sealing; vacuum injection of electrolyte; ring sealing ring sealing; multi-unit series packaging. The invention uses the elastic flange structure to realize the flexible packaging of the supercapacitor. The packaged device has a certain compressibility in the thickness direction under mechanical action, which provides convenience for the application of the supercapacitor in the field of special mechanical environments such as flexible electronics. . In addition, the present invention uses an annular sealing ring structure to realize airtight packaging of the liquid injection port of the supercapacitor, which can effectively reduce the phenomenon of electrolyte volatilization and failure during long-term storage of the supercapacitor, and prolong the storage life of the device.

Description

technical field [0001] The invention belongs to the technical field of supercapacitor preparation, in particular to a flexible packaging method for supercapacitors with a laminated structure. [0002] technical background [0003] Supercapacitor is a widely used electrochemical energy storage device, which has significant advantages such as high power density, long cycle life, and strong environmental adaptability. It has been widely used in electric vehicles, consumer electronics and other fields. [0004] The packaging process is a key process step in the manufacturing process of supercapacitors. Its function is to isolate the electrochemical environment inside the supercapacitor from the external environment. Through the sealing process, the long-term slow volatilization of the electrolyte inside the device is prevented, and the stability and stability of the supercapacitor are guaranteed. long-term effectiveness. [0005] With the development of flexible electronics tech...
