Description

Technical Field

[0001] The utility model relates to the technical field of battery cell production, in particular to a thermal oxygen oxidation device for battery cell production. Background Art

[0002] During the production and processing of battery cells, the silicon wafers for producing battery cells need to be placed in an electrolytic cell for thermal oxygen oxidation treatment, so that a dense silicon dioxide film is produced on the surface of the silicon wafers for producing the battery cells. The characteristic that alkaline solution does not easily react with silicon dioxide is used to protect the positive surface during the polishing process to prevent alkaline polishing from corroding the positive SE and damaging the raw and auxiliary materials.

[0003] However, when the existing thermal oxygen oxidation device for battery cells is in use, since the electrolytic cell used for the oxidation device is usually operated in an open environment, the oxidizing solution in the electrolytic cell is prone to volatilization during the oxidation process, which not only pollutes the working environment but also affects the health of the staff. Secondly, after the silicon wafers for producing battery cells are oxidized by the solution in the electrolytic cell, a large amount of oxidizing solution is attached to the surface when the silicon wafers are taken out and drip onto the surface of the workbench, which not only causes waste but also requires the staff to clean it up, increasing the work intensity of the staff. In view of the above problems, the inventor proposes a thermal oxygen oxidation device for battery cell production to solve the above problems. Utility Model Content
