MATERIALS
additives are added to the plasma via a special nozzle head, depending on the application. This plasma polymerisation allows the substances to optimally adhere to the material surface during plasma coating, to bind firmly and to crosslink with each other. The result is a nanolayer with functional surface properties that can be individually tailored to the process. One example is the PlasmaPlus application AntiCorr for anti-corrosion coatings on sealing and adhesive grooves on battery housings.
PLASMA TREATMENT FOR BATTERY MANUFACTURING These days, Plasmatreat’s plasma technology is used for all kinds of batteries: prismatic, cylindrical and pouch cells. These areas of application are extremely wide. For example, optimisation of electrical insulation can be achieved via plasma cleaning prior to coating or the covering of individual cells with PET film. In cell-to-cell bonding - adhesion of individual cells to the battery module - plasma treatment activates the cell surfaces after application of the coating or the film covering, thereby improving adhesion and thus thermal conductivity. The adhesiveness of structural
bonding in a battery module, for example of the side walls, can be increased through plasma treatment of the components. Plasma technology
Plasma pretreatment technology is used for all kinds of batteries
is also used for cleaning battery terminals before contact (wire bonding) as well as for coating the overall housing of the battery module for active corrosion protection or treatment of power electronics prior to application of the protective coating (conformal coating).
INTEGRATION IS KEY Plasmatreat’s plasma systems and system components for its Openair-Plasma technology can be integrated into existing production lines and require only pressurised air and electricity for operation. In many cases, they represent an alternative that is less harmful to the environment. In battery manufacturing, for example, they replace solvent-containing processes in adhesion or aggressive chemical processes that are used to protect against corrosion, such as galvanisation. Supplemented by the high-tech plasma control unit (PCU) and innovative add- on modules for monitoring and diagnosing all process parameters, Plasmatreat offers its customers seamless process controlling, consistently high quality and precise reproducibility of applications.
