[0002] The electrolyte is the carrier of ion transmission in the battery equipment. The electrolyte is generally prepared from high-purity organic solvents, electrolyte salts, necessary additives and other raw materials under certain conditions and in a certain proportion; Inject the electrolyte into its interior. The quality of the cell injection process directly determines the quality of the cell. In order to ensure that the electrolyte in the cell is fully filled and infiltrated, it is usually necessary to evacuate the cell before the cell is injected. The air in the battery cell, and then the liquid injection operation of the battery cell, the process is cumbersome and time-consuming, which greatly affects the production efficiency of the battery cell
