Improve the adhesion of battery cell blue film

Before assembling the battery cells, in order to prevent safety accidents in potassium batteries, it is generally necessary to apply external adhesive treatment to the potassium battery cells. The function of adhesive coating is not only to fix, but also to insulate and dissipate heat, prevent short circuits, protect circuits, and prevent scratches. Performing plasma cleaning on both the front and back of the battery cell and end plate can clean the surface of the battery cell blue film from dirt, roughen the surface of the battery cell blue film, and improve the adhesion of adhesive or coating.

Cleaning before welding the extreme ear

During the factory production process, the battery cells of automotive power carp batteries may experience unevenness, bending, and even twisting, resulting in virtual welding, false welding, short circuiting, and other phenomena during welding. After leveling the electrode ears of the battery cell, cleaning the surface of the electrode ears with a plasma cleaning machine can remove impurities such as organic matter and small particles, and roughen the welding surface to improve the reliability of subsequent laser welding.

Aluminum shell of battery cell

With the rapid development of new energy vehicles, square shell battery cells are widely used as the most commonly used power module in various new energy electric vehicle power battery modules. Due to the need to stick insulation pads on the surface of the aluminum shell of the battery cell, the surface of the lithium battery module battery cell needs to be cleaned using plasma cleaning equipment to ensure a smooth and accurate sticking. On the one hand, plasma cleaning can remove surface pollutants such as oil stains, and on the other hand, it can enhance the surface energy of the aluminum shell and improve the adhesion between the adhesive and the adhered surface.
