Embodiment Construction

[0030] 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.

[0031] The flexible packaging method of the supercapacitor with a stacked structure includes a single package and a multi-cell series package;

[0032] 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:

[0033] (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 of a laminated structure supercapacitor, and belongs to the technical field of supercapacitor preparation. The method comprises the steps of singlebody packaging and multi-single-body series packaging, and specifically comprises the following steps of constructing a laminated structure to be placed; sealing a flange structure; performing electrolyte injection in a vacuum mode; sealing an annular sealing ring; and carrying out multi-single-body series packaging. By means of the elastic flange structure, flexible packaging of the supercapacitor is achieved, and the packaged device has certain compressible capacity in the thickness direction under the mechanical action, and convenience is brought to application of the supercapacitor in thefield of special mechanical environments such as flexible electronics and the like. In addition, due to the adoption of the annular sealing ring structure, the airtight packaging of the supercapacitorliquid injection port is realized, so that the volatilization failure phenomenon of the electrolyte in the long-term placement process of the supercapacitor can be effectively reduced, and the storage life of the device is prolonged.

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. technical background [0002] 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. [0003] 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. [0004] With the development of flexible electronics technology, ...
