[0002] Now there is a patent number: CN201820649542.5 A lithium battery electrolyte installation device, the utility model discloses a lithium battery electrolyte installation device, including: liquid storage tank, liquid separation tank, degassing device, liquid injection Device, battery cell clamping device, in actual use, the liquid separation tank absorbs the lithium battery electrolyte from the liquid storage tank under the action of the vacuum pump, and the gas in the solution is removed by the degassing device, which can effectively reduce injection. When the liquid is released, bubbles are generated, and then under the action of the vacuum pump, the lithium battery electrolyte enters the liquid injection device. After the liquid injection device is installed in conjunction with the battery cell clamping device, it is completely in a sealed state to reduce gas entry, and Through the control of various valves and vacuum pumps, the liquid separation tank can absorb the lithium battery electrolyte from the liquid storage tank at the same time as the liquid injection, which can not only control the liquid injection volume and reduce the generation of air bubbles during liquid injection, Also improved liquid injection efficiency, but this device is not convenient for carrying out layered sampling to lithium battery electrolyte
