AI Technical Summary

Technical Problem

The welding of existing battery tabs to the cover plate can easily lead to the tabs being inserted in reverse, resulting in a risk of internal short circuits in the battery and affecting safety and performance.

Method used

Design a cover plate assembly, including a cover plate and a lower plastic part, which is connected to the electrode tab by a protective body. The protective body has a protective cavity and an opening, the main body has a buckle, and the bent part has a rubber reduction groove to ensure the electrode tab is fixed and the protective effect is achieved.

Benefits of technology

It effectively prevents reverse insertion of the tabs, reduces the risk of internal short circuits, improves battery safety performance, reduces manufacturing costs, and enhances market competitiveness.

Abstract

The application relates to the battery technical field and provides a cover plate assembly and a battery. The cover plate assembly of the application is applied to a battery shell and comprises a cover plate provided with pole columns and a lower plastic arranged on the cover plate. The cover plate is in a strip shape, the pole columns are arranged at intervals along the length direction of the cover plate, and the pole columns are used for being connected with the tabs of a pole group. The lower plastic comprises an integral main body, a protection body, a bending part for connecting the main body and the protection body together, the main body is in a strip shape and is shaped along the cover plate, and the protection body and the bending part are arranged on one side of the main body in the length direction. The protection body can be bent to one side of the main body through the bending part and is connected with the main body through clamping, and the connected protection body is arranged on the side of the pole columns away from the cover plate and abuts against the tabs. The cover plate assembly of the application can play the roles of shaping and fixing the tabs, prevents the tabs from being inserted into the pole group in reverse and causing internal short circuit of the battery, and is favorable for improving the safety performance of the battery.
