THE PROS OF
Surface treatment with plasma technology can increase effi ciency, lower costs, and reduce environmental harm within battery manufacturing
lasma applications make it possible to optimise battery manufacturing for electric vehicles (EVs). Besides
vacuum plasma, the atmospheric plasma technology Openair-Plasma for pretreatment of surfaces is used in various processes to help make a number of production steps more eff icient and more eco-friendly. Mobility-related changes mean
that the need for high-performance batteries for EVs is rapidly increasing. Plasmatreat’s plasma technology is based on a simple physical principle: The addition of energy causes the
states of matter to change. Solids become liquids, and liquids become gases. If additional energy is added to a gas, it ionises and becomes energised plasma, the fourth state of matter. If the plasma, with its high energy level, subsequently comes into contact with materials, the surface properties of those materials may change. The wettability of the surface increases and a hydrophobic surface may become hydrophilic. As a result, adhesives, paints, varnishes or seals adhere optimally to the surface. Plasma pretreatment is the key technology for microfi ne cleaning,
activation, and coating of practically all materials. In that sense, it is a universal problem-solver: Plasma facilitates the industrial use of entirely new materials and material combinations, as well as the use of solvent-free paints and adhesives. It also makes processes more eff icient and environmentally friendly, particularly battery manufacturing. Openair-Plasma is Plasmatreat’s
atmospheric plasma nozzle technology. If Openair-Plasma is not suff icient for optimum adhesion, a plasma coating can provide a remedy in many cases. One example is the PlasmaPlus technology developed by Plasmatreat, which uses nanocoatings to create specifi cally functionalised surfaces on various die casting alloys or aluminium materials. These can be both superhydrophobic and superhydrophilic, for example. Specifi c
