With the increasing promotion of new energy vehicles, we also see more and more new energy vehicles on the road. The core of new energy vehicles is undoubtedly the battery. In order to pursue carbon neutrality and energy saving and emission reduction, electric energy is undoubtedly worth vigorously promoting; So in the battery industry, what can plasma cleaners do with their surface treatment?

Why does the blue film of new energy vehicle battery use plasma surface treatment

The more common is the battery blue film, lithium battery after the completion of production will be put into the aluminum shell wrapped in blue film, to provide a stable and reliable space for the cell work; So in the production of blue film need to paste well, can not produce bubbles, paste is not strong, flatness and so on; These problems will affect the quality of batteries, inferior batteries are used in new energy vehicles, will produce a lot of problems; So the aluminum shell is pretreated with plasma cleaning machine before pasting to remove the microscopic pollutants on the surface and enhance the surface activity, which can make the paste more firm. Make the shell conform to the production standard, improve the quality and production efficiency of the cell.

So what does the whole process look like?

First of all, we use plasma cleaning machine for surface cleaning to remove organic pollutants and oxides on the surface. The whole process only works on the surface of the material without any erosion on the interior, so as to obtain ultra-clean surface. Then the activation of the surface, the whole process will change the chemical properties of the surface, enhance the surface adhesion, adhesion; After plasma cleaning machine processing can become more excellent bonding.
