VON ARDENNE has identified different technological approaches that improve the performance and cost-efficiency of lithium-ion batteries.
One example is the PRIMER Layer that is deposited on the current collector foil. For this purpose, VON ARDENNE offers a solution based on physical vapor deposition (PVD) which creates layers with reliable adhesion and improved electrical properties.
During several tests, our results showed improved contact resistance and anti-corrosion behavior, electro-chemical stability and mechanical adhesion and cycle lifetime. These effects led to higher cell performance and power density.
Apart from these thin-film technologies, VON ARDENNE is working on new, innovative vacuum thick-film technological approaches for different parts of a battery cell.
As your partner in joint development, we can ensure you quick success thanks to our expertise in technology development and the manufacturing of equipment for research purposes, pilot production and industrial large-area coating projects with plasma-enhanced deposition methods.
The FOBA is a coating system for the roll-to-roll coating of flexible
materials. It uses our proven electron beam evaporation technology to deposite functional layers at high rates on polymer film or thin metal foil, for instance for holographic applications, battery applications and next-generation packaging.

VON ARDENNE PRESENTS REFINEMENT OF CURRENT COLLECTORS FOR LITHIUM-ION BATTERIES AT BATTERY JAPAN 2019 IN TOKYO
VON ARDENNE has been a leading company in industrial large-area coating using innovative PVD methods. Based on this expertise in the deposition of extremely thin layers, we have identified different approaches along the production chain of lithium-ion batteries to considerably improve their performance and cost-efficiency by functionalizing cell component surfaces.
These technologies enable solutions that address current challenges for lithium-ion batteries. In the face of the increasing demand, for instance in the automotive industry, requirements such as output, high energy density, longevity and fast-charging capacity are getting increasingly important. At the same time, we are tackling the challenges that occur when new cell systems and innovative electrode manufacturing processes shall be established. Here, PVD thin-film technologies offer cell manufacturers a high potential for a cost-efficient, sustainable production that helps save resources.
