Battery

Abstract

The invention provides a battery which comprises a cover plate assembly, a conductive shell and a battery cell, wherein the cover plate assembly is arranged on the conductive shell, and the battery cell is located in a cavity of the conductive shell. The cover plate assembly comprises a conductive top cover and a cover plate, the cover plate is in sealing connection with the conductive shell, and the conductive top cover and the cover plate are in insulating connection through an insulating part. The cover plate assembly further comprises a continuous welding seam, the continuous welding seam comprises a head end, a main body section and a tail end which are sequentially connected, the main body section continuously extends to the tail end from the head end, namely, the formed continuous welding seam is a continuous and uninterrupted welding seam and is continuously formed in one-time welding instead of being formed in a splicing mode, the phenomenon of welding seam overlapping is reduced or avoided, therefore, the continuous welding seam has lower heat, and the problem that the insulating part is heated and melted can be effectively reduced or avoided, so that the finished product yield of the battery is improved.

Description

Technical field [0001] The present invention relates to the field of battery structures, in particular, to a battery. Background technique [0002] The battery refers to a small device that can convert chemical energy into electrical energy, such as a button battery, usually used in electronic devices such as electronic meter, Bluetooth headset, electric toy, to provide power sources for electronic devices, occupying very well in daily work and life. Important position. [0003] Taking the button battery as an example, there is mainly including a conductive housing and a cover assembly, where the cover assembly and the conductive casing are formed with a cavity, and the cover assembly includes a conductive top cover and a cover, in the conductive top cover and cover. An insulating member is provided between the boards to isolate the conductive top cover and the cover. On the cover assembly, there is usually a weld, such as a connecting weld between the cover assembly and the cond...

AI Technical Summary

Problems solved by technology

[0005] The invention provides a battery to solve the problem that in the existing batteries, the overlap between the welding seams on the cover plate assembly will lead to high heat accumulation, which will easily cause the insulating part between the conductive top cover and the cover plate to be heated and melted, thereby reducing the The problem of battery yield
