Insulated sealing structure of electrode

Abstract

The invention discloses an insulated sealing structure of an electrode. An insulated sealing body of the insulated sealing structure of the electrode is an insulated sealing cover which is sheathed on the periphery of a lead-out structure of the electrode. One end of the insulated sealing cover is erected on the end face of a cell at the back of the lead-out structure of the electrode and the periphery of the cell is sheathed with the other end of the insulated sealing cover. A positioning wrinkle which is matched and complementary with a deforming wrinkle and is embedded into a groove is arranged at the periphery of the middle part of the insulated sealing cover. Thus, the integrated insulated sealing cover is adopted to separate the lead-out structure of the electrode from a shell. The periphery of the lead-out structure of the electrode can be sheathed with the insulated sealing cover conveniently and rapidly and the insulated sealing cover is pressed tightly against the lead-out structure of the electrode by virtue of a seal turned edge and the deforming wrinkle, so that the assembly process is simplified, the assembly cycle is shortened, the assembly efficiency is increased, the loss of materials in power storage devices is reduced and the manufacturing cost is reduced.

Description

technical field [0001] The invention relates to the technical field of electrode insulation and sealing, in particular to an electrode insulation and sealing structure of a battery or a supercapacitor. Background technique [0002] At present, the commonly used energy storage components (including batteries and supercapacitors) have electrode lead insulation and sealing structures such as figure 1 As shown, the energy storage component is composed of a cell 01, a casing 02, an electrode lead-out structure and an insulating sealing body. The casing 02 is electrically connected to the lower end of the cell 01, and the electrode lead-out structure is conductively connected to the upper end of the cell 01. Therefore, an insulating sealing body needs to be interposed between the electrode lead-out structure and the casing to avoid short circuit problems caused by the contact between the electrode lead-out structure and the casing 02 . In the specific structure, the shell 02 is p...

Problems solved by technology

[0012] Therefore, the reason for the installation sequence of the parts in the existing production technology must be to use three insulating and sealing components to combine to achieve sealing and insulation; and in terms of production process comparison, the assembly process of the insulating and sealing structure of the energy storage device in the prior art is relatively long. The production efficiency is low, and because the assembly error of the three separate insulating and sealing components during use will affect the insulating and sealing performance of the entire insulating and sealing body, so that there are many potential uncertain factors in the energy storage device, That is, the defect of any part or the negligence of the assembly process will lead to the failure of the insulation seal of the monomer
