Embodiment 1

[0033] Combining the above-mentioned gel positive and negative flexible batteries with specific practices in reality, the corresponding elaboration is made as follows: A gel positive and negative flexible battery includes a positive electrode 1, a positive electrode tab 13, an isolation glue layer 3, and a negative electrode 2. Negative pole tab 23, the positive pole and the negative pole are glued together through an insulating adhesive layer, and the edges of the positive pole and the negative pole are sealed; the positive pole is connected to the positive pole tab, and the negative pole is connected to the negative pole tab. exposed on the outside.

[0034] Specifically, a tab treatment layer 4 is provided on the surfaces of the positive tab 13 and the negative tab 23 , and the tab treatment layer 4 is a corona layer. The corona power used in this embodiment is 900w, and the corona treatment time is 3 seconds.

[0035] Specifically, the positive electrode 1 includes a posi...

Embodiment 2

[0043] The basic settings of the first embodiment and the second embodiment are the same, the main difference is that the negative electrode carrier 21 is nickel foil.

Abstract

The invention discloses a gel positive and negative electrode flexible battery, comprising a positive electrode (1), a positive electrode lug (13), an insulating adhesive layer (3), a negative electrode (2) and a negative electrode lug (23), wherein the positive electrode and the negative electrode are bonded through the insulating adhesive layer, and the edges of the positive electrode and the negative electrode are sealed; The positive electrode is connected with the positive electrode ear, the negative electrode is connected with the negative electrode ear, and the positive electrode ear and the negative electrode ear are exposed on the outside; As that isolate adhesive layer is adopt to directly bond the positive electrode and the negative electrode together, the main body is more firm, reliable and safe; moreover, the isolating adhesive layer itself has a swelling function, can adsorb a certain amount of electrolyte, improve the interface of the battery, realize high safety, longservice life and the like.

Description

technical field [0001] The invention relates to the field of lithium battery manufacturing, in particular to a gel positive and negative electrode flexible battery. Background technique [0002] With the continuous development and improvement of ultra-thin lithium batteries, the structure of existing lithium batteries can no longer meet the needs of microelectronic devices, especially the isolation film inside the existing lithium batteries. Conventional flexible lithium batteries are assembled with a positive electrode, a separator layer, and a negative electrode, but this may cause relative sliding, is not firm, and affects product quality. Contents of the invention [0003] The technical problem solved by the present invention is to provide a gel positive and negative electrode flexible battery. The present invention uses the isolation adhesive layer to directly bond the positive electrode and the negative electrode together, so that the main body is more firm, reliable...
