An integrated cover plate and a secondary battery using the cover plate

Abstract

The invention discloses an integrated cover plate and a secondary battery adopting the above cover plate. The stop frame is pre-fixed and installed under the base plate, which ensures the fixing reliability of the stop frame and the base plate during assembly, and reduces the trouble in the battery assembly process. The installation process of the stopper frame improves the assembly efficiency, effectively prevents the winding core from moving in the shell, avoids the damage of the winding core during the up and down movement, and reduces potential safety hazards; in the further design, the stopper frame and the base plate pass through the insulation The riveting is fixed to improve the installation reliability of the two, and at the same time, it effectively solves the problem that the stop frame and the battery cover are not firmly matched.

Description

technical field [0001] The invention relates to the technical field of battery processing, in particular to an integrated cover plate and a secondary battery using the cover plate. Background technique [0002] With the development of modern society and the enhancement of environmental awareness, more and more devices choose secondary batteries that can be recharged and recycled as power sources, such as mobile phones, notebook computers, electric bicycles, electric vehicles, etc. The application and development of batteries provide a broad space. Especially in recent years, under the guidance of relevant national policies, electric vehicles have embarked on the road of rapid development, which has created opportunities for the development of secondary batteries, especially power batteries, and also put forward higher requirements for the performance of secondary batteries. requirements. [0003] In order to prevent the winding core inside the secondary battery from being ...

AI Technical Summary

Problems solved by technology

However, the currently commonly used stop frame and the cover plate are separated. Although the stop frame can control the movement of the winding core to a certain extent, the stop frame itself is unconstrained, resulting in the up and down of the winding core and the stop frame. risk of movement

This will cause the winding core to be damaged in the process of moving up and down, causing potential safety hazards

[0004] At the same time, when the stop frame and the cover plate are separated, the production process of assembling the battery increases the process of installing the stop frame, increases labor costs, reduces production efficiency, and virtually increases costs.
