HIGH-PERFORMANCE COATINGS FOR THE FUTURE OF MOBILITY: VON ARDENNE AT THE IAA 2019 IN FRANKFURT
With decades of experience in the development and manufacturing of vacuum coating systems, VON ARDENNE has developed into a leading equipment provider for the architectural glass and photovoltaics industry on a global level. But the high-tech solutions provided by the German family-owned company, which is based in Dresden, are also used in many other industries.
During the New Mobility World at the IAA 2019 in Frankfurt, Germany, VON ARDENNE will introduce its latest developments for the future of mobility, such as innovative solutions for lithium-ion batteries and fuel cells, automotive glazing, displays or sensor technology. VON ARDENNE will show how ultra-thin coatings will provide materials with new functional surface properties and contribute to saving and storing energy and why they enable certain highly advanced electronics in the first place.
High-performance and cost-efficient lithium-ion batteries with the help of PVD coatings
High output, high energy density, longevity, fast-charging capacity as well as a sustainable and resource-saving manufacturing process: all these are requirements imposed on modern lithium-ion batteries and their production. With XPRIME, a specially developed physical vapor deposition (PVD) technology, VON ARDENNE offers a suitable solution. XPRIME is an ultra-thin (<100 nm) carbon coating on aluminum or copper current collectors. This coating increases the conductivity of the current collector and, thereby, reduces the through-plane resistance between the current collector and the electrode coating. The result is an increased power density and the lifetime of the battery cell.
XPRIME enables the passivation of the current collector and increases its electro-chemical stability, which is needed in high-voltage or all-solid-state batteries. Furthermore, the technology increases the chemical stability against corrosive media the current collector might be exposed to due to improper storage or during a water-based electrode production.
