Abstract

The invention discloses a battery cell connection method, a battery production device and a battery, and relates to the technical field of battery production. The battery cell connection method comprises the following steps: pressing a plurality of tabs of a battery cell so as to draw close the tabs to form a connection part; connecting the parts of the plurality of tabs in the connecting part; and connecting the adapter sheets to the respective connecting parts of the two battery cells. The battery cell connection method has the characteristic that the safety performance of the battery can be improved. The battery production device adopts a battery cell connection method to connect the tabs, and the battery production device also has the characteristic of improving the safety performance of the battery. The tabs of the battery cells of the battery are connected by adopting a battery cell connecting method, and the battery has the characteristic of relatively high safety performance.

Description

technical field [0001] The present invention relates to the technical field of battery production, in particular, to a battery cell connection method, a battery production device and a battery. Background technique [0002] In the battery production process, it is necessary to weld the tabs of the processed cells and the adapter sheet together, combine the welded cells, and weld the adapter sheet to the pole on the top cover of the battery. However, in the process of cell assembling, etc., the tabs are prone to be bent or shifted, and there is even a risk that the displaced tabs come into contact with the pole pieces, resulting in a short circuit of the battery. [0003] In view of this, it is particularly important to develop and design a cell connection method, a battery production device and a battery that can solve the above technical problems. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provide a battery cell connection method which h...
