Contact angle measurement before and after power battery bonding
In the battery assembly process, in order to prevent the battery from short-circuiting and play the role of insulation, it is necessary to apply glue to the battery cell to improve the safety of use. Plasma treatment of insulating plates, end plates, PET films and other parts with a plasma cleaning machine before gluing can thoroughly clean the surface of the cell, roughen the surface of the cell, and improve the adhesion of subsequent gluing or gluing.
Plasma cleaning technology is the most thorough stripping cleaning method among cleaning methods. Its biggest advantage is that there is no waste liquid after cleaning. The biggest feature is that it can handle metals, semiconductors, oxides and most polymer materials well. To achieve overall and partial cleaning and complex structures.
In order to give you a more intuitive understanding of the plasma cleaning effect, the following is a comparison of the contact angle test and dyne pen test data before and after the plasma treatment of the power battery aluminum shell and the power battery blue film.

Through the analysis of the actual data of the test, it is proved that the plasma cleaning technology can clean the dirt on the surface of the cell, roughen the surface of the cell and improve the adhesion of the glue or glue.
