Research Topics

The focus of the research is both the development of improved materials and components, and the fundamental understanding of the functioning of these components for energy storage and conversion.In the field of battery research alternative concepts for lithium ion batteries are developed. For future generations of batteries the focus is on metal air batteries with significantly improved energy density.
Within the research on fuel cells (SOFC) and steam electrolysers (SOEC) the main goal is lowering the operating temperature.
Cross cutting issues between batteries and fuel cells are centered around the study of efficient electro-catalytic materials for the oxygen reduction and evolution on the basis of transition metal components. Research: Research Topics …


Kopernikus Supports Transformation of Energy Sector

The „Energiewende“ provides the expansion of renewable energies. To use the opportunities associated with this transformation and minimize their risks, it requires the development of economic concepts for usage and storage of electricity from fluctuating renewable energy sources. These concepts are summarized under the term „Power-to-X“. They show a special potential to reduce the use of fossil fuels in the essential sectors of the German industrial location, namely power and energy, transportation and traffic and chemicals.
The Kopernikus project “Power-to-X” faces this challenge by creating points of interconnection between energy supply and material value creation. More: Kopernikus Supports Transformation of Energy Sector …

New Batterytyp

A focal point of the research in the IEK-9 is the development of metal-air batteries. New insights in the functioning of the environmentally friendly silicon-air battery are recently published in two scientific publications. More: New Batterytyp …



A further major activity in IEK-9 is the development of high-temperature fuel cells and electrolysers. The knowledge of the kinetics and mechanisms gained by investigation of the electrode processes is used for the development of novel electrolyte and electrode materials, which should make operation of the SOFC at temperatures below 600 °C with sufficient performance characteristics feasible.
