Fraunhofer IKTS is specialized in designing tailored electrode recipes, processing techniques, and architectures to deliver superior electrochemical performance. Our research tackles key challenges in energy density and power density, cycling stability, and manufacturing compatibility. To enhance lithium-ion battery efficiency, we focus on structured electrode designs that improve ion transport, reduce polarization, and ensure uniform active material utilization, enabling higher energy and power densities.

Aligned with our commitment to sustainability, we advance water-based, fluorine-free binder systems for cathodes, reducing environmental impact while maintaining mechanical and electrochemical stability. By driving innovation, fostering collaboration, and prioritizing sustainability, we develop next-generation lithium-ion batteries to power electric vehicles, renewable energy systems, and beyond.

In addition, other battery chemistries, such as aluminum-ion batteries (AIB), are being developed at Fraunhofer IKTS, aligning with our mission to create sustainable energy storage systems using non-critical and non-toxic metals.

Fraunhofer IKTS is also exploring the development of highly porous electrodes for water treatment applications, with a particular focus on metal extraction. This work underscores our dedication to addressing environmental challenges through advanced materials and innovative processes.
