Compared with the traditional method of spraying through a nozzle, this device can reduce the amount of passivation liquid used, accurately coat the passivation liquid on the end of the battery cell 10, and make the passivation liquid evenly coated.

[0043] According to a further optimization scheme, the liquid separation device 8 includes a liquid separation plate 801, a liquid separation groove 802 is provided on the top of the liquid separation plate 801, and the length of the liquid separation groove 802 matches the length of the liquid separation plate 801;

[0044] The liquid separation plate 801 is provided with a plurality of liquid guide holes 803, which are located on one side of the liquid separation groove 802, and are evenly arranged along the length direction of the liquid separation groove 802.

[0047] The liquid outlet ends of the two liquid outlet pipes 5 are symmetrically arranged on the corresponding liquid separation grooves 802 .

[0048] When in use, the liquid inlet pipe 4 is connected with the passivation liquid storage box. Under the action of the diaphragm pump, the passivation liquid in the passivation liquid storage box can enter the three-way valve 3 through the liquid inlet pipe 4. The flow rate valve is used to detect the flow rate of the passivation liquid and feed the flow rate back to the diaphragm pump. The flow rate of the passivation liquid can be adjusted by adjusting the diaphragm pump. The passivation liquid first enters the three-way valve 3 and is then pumped out through the two liquid outlet ends. The liquid outlet ends of the three-way valve 3 are connected with the liquid outlet pipe 5.

Compared with using a nozzle to spray the passivation liquid, the method of applying with the sponge 905 can accurately control the application area and will not cause waste of the passivation liquid.
