Can the atmospheric plasma cleaner be used for the PET film of the lithium battery?
In the production and manufacture of automobile power lithium batteries, many of them need to be processed by atmospheric plasma cleaning machines. Not only the positive and negative electrodes, tabs, etc. of the lithium battery described above, but also the low-temperature plasma surface treatment machine. During the battery assembly process, the PET film in the lithium battery assembly must also be plasma surface treated. Let us talk about the role of the atmospheric plasma cleaning machine in the assembly of automotive lithium batteries in detail.
Several battery cells are connected in series and parallel to form an automobile power lithium battery module, which is an element of the battery pack. In order to play the role of insulation during the assembly process of battery components, protect the circuit, prevent scratches, and prevent short circuits, it is particularly necessary to externally paste the battery cells to prevent safety accidents during use of the lithium battery. The atmospheric plasma cleaning machine performs external paste treatment on metal surfaces and insulating materials, such as insulating plates, end plates, PET films, etc., to thoroughly remove dirt on the surface of the material, roughen the surface of the material, and prepare for the next gluing process , Improve the adhesion of paste or glue. Below we will verify the PET film through plasma treatment experiments.

The PET film of automobile power lithium battery was tested using an atmospheric jet rotary plasma surface treatment machine. The results showed that under different parameter settings, the hydrophilicity of the PET film after plasma treatment is different, and the production parameters Can be determined according to the actual situation.
Based on this, on the basis of the original mature technology, the actual production of atmospheric plasma cleaning machine needs to have good stability and reliability, and can be matched with the original automatic production equipment. Therefore, On the basis of the original technology mature equipment, in accordance with the actual production technical requirements, in addition to the on-site layout of the automotive power lithium battery surface treatment production line, related additional functions have also been added to ensure the plasma cleaning effect and the plasma surface treatment machine Stability, meets many requirements such as parameter collection, data transmission, long-distance operation, and safety and environmental protection.
