Shell structure, battery and packaging method thereof

Abstract

The invention belongs to the technical field of battery production and manufacturing, and particularly discloses a shell structure, a battery and a packaging method thereof. The shell structure comprises a cover body and a shell body, wherein the cover body is provided with a first connecting part, the first connecting part is arranged on the side surface of the cover body in a surrounding mode, the shell body is provided with a second connecting part used for being matched with the first connecting part, the first connecting part and the second connecting part abut against each other and are matched to form an annular groove, and the annular groove is used for injecting a glue solution. According to the shell structure provided by the invention, the annular groove is formed in the surfaces of the cover body and the shell body, and the glue solution is injected and filled in the annular groove, so that the traditional laser welding is replaced, the problem that the K value of a battery core is poor due to the fact that chippings easily fall into a roll core when an upper shell and a lower shell of a steel shell battery are packaged is solved, the packaging effect is good, and the phenomenon that chippings are generated when the upper shell and the lower shell are packaged can be effectively avoided so as to ensure the excellent electrical property of the battery and improve the quality of the produced battery.

Description

technical field [0001] The invention belongs to the technical field of battery production and manufacturing, and in particular relates to a casing structure, a battery and a packaging method thereof. Background technique [0002] With the rapid development of science and technology, portable electronic products such as mobile phones, tablet computers, and notebook computers have become mainstream products in society. As part of the rapid popularization of electronic products, the demand for batteries is also increasing. [0003] Compared with the currently commonly used aluminum-plastic film soft-pack batteries, steel-case batteries have: [0004] 1. Reduce the width of the top and side seals, which can increase the space utilization rate, so that the energy density of the battery cell is higher; [0005] 2. Good safety, the battery has high reliability in the extreme environment. [0006] Therefore, steel case batteries have great application prospects, and research on t...

AI Technical Summary

Problems solved by technology

[0010] The purpose of the present invention is to solve the problem that the upper and lower shells of the steel shell battery are prone to debris falling into the winding core during packaging by providing a shell structure, battery and packaging method thereof, resulting in poor K value of the battery cell , its encapsulation effect is good, and it can effectively avoid the phenomenon of debris generated when the upper and lower shells are encapsulated, thereby ensuring the excellent electrical performance of the battery and improving the quality of the produced battery
