Problems solved by technology
In the production process of the lithium battery in the related art, the electrolyte needs to be injected through the liquid injection hole opened thereon. Since the position of the liquid injection hole is fixed, the distribution of the liquid entering the chamber from the liquid injection hole is not uniform, and the coverage area is not uniform. Small, resulting in slower absorption (about 20-30 minutes to complete the injection)
In addition, since the cover plate has been welded on the cup where the battery is placed before the liquid injection, the air pressure in the cavity will gradually increase during the liquid injection process, which in turn hinders the absorption speed of the liquid
This is less productive

The invention relates to a battery cell liquid injection method and a lithium battery liquid injection device. The battery cell liquid injection method is used for the lithium battery liquid injection device, the lithium battery liquid injection device comprises a liquid injection structure and a shell, the liquid injection structure comprises a liquid injection head, the shell is provided with a containing groove, a battery cell is arranged in the containing groove, and a liquid injection opening communicated with the containing groove is formed in the shell; and the liquid injection opening is arranged around the liquid injection head. The liquid injection method comprises the following steps: moving the liquid injection head to the position above the liquid injection opening; and controlling the liquid injection head to move above the liquid injection opening along a preset first path, and simultaneously controlling the liquid to be output from the liquid injection head so as to be injected into the containing groove through the liquid injection opening. According to the liquid injection method, when the liquid injection head is used for liquid injection, the liquid injection head can be controlled to move above the liquid injection opening along the preset first path, so that the liquid (electrolyte) entering the shell can be distributed more uniformly, the coverage area is large, the liquid absorption speed of the battery cell can be increased, the liquid injection time is shortened, and the production efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of lithium battery liquid injection, in particular to a battery cell liquid injection method and a lithium battery liquid injection device. Background technique [0002] With the development of modern society, the application of lithium batteries is becoming more and more extensive. In the production process of the lithium battery in the related art, the electrolyte needs to be injected through the liquid injection hole opened thereon. Since the position of the liquid injection hole is fixed, the distribution of the liquid entering the chamber from the liquid injection hole is not uniform, and the coverage area is not uniform. Small, resulting in slow absorption (about 20-30min to complete the injection). In addition, since the cover plate has been welded to the cup where the battery is placed before the liquid injection, the air pressure in the cavity will gradually increase during the liquid injection pro...
