Abstract

The invention belongs to the technical field of cylindrical batteries, and discloses a battery assembly and a battery manufacturing method. The battery assembly comprises a shell, an adapter plate and a cover plate. The interior of the shell is hollow, one end of the shell is open, the cylindrical battery cell is mounted in the shell, and the shell is circumferentially recessed to form a circumferential inner groove; the adapter plate is mounted on the cylindrical battery cell, and one axial end of the adapter plate is pressed between the circumferential inner groove and the cylindrical battery cell and is propped against the circumferential inner groove and the cylindrical battery cell; the cover plate abuts against the other axial end of the switching piece, and the opening end of the shell is bent inwards to position the cover plate. And the switching sheet and the shell are fixedly connected in a mechanical matching connection mode, so that the processing difficulty and the cost are low, and batch production and manufacturing are facilitated. The battery manufacturing method disclosed by the invention is used for producing and manufacturing the battery assembly, the connection between the switching piece and the shell can be realized without intervention of laser welding, thermal damage of each part is avoided, the production difficulty is reduced, and the production efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of cylindrical batteries, in particular to a battery assembly and a battery manufacturing method. Background technique [0002] At present, the large cylindrical lithium-ion battery mainly adopts the all-pole design scheme, and the connection method between the cylindrical battery adapter and the battery case mostly adopts the method of laser welding to connect the adapter and the case to achieve the purpose of charging the case. However, the connection method of laser welding has high processing difficulty and high precision control, and there is a risk of welding through and undetectable. Moreover, laser welding will knock off the shell coating of the cylindrical battery case, making the case prone to rust and other problems. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a battery assembly and a battery manufacturing method, which can realize the connection ...
