Long-term energy storage is one of the key challenges for the success of the Energy Transition. The lithium-ion battery continues to be the standard for mobile applications. Researchers at Forschungszentrum Jülich are working on increasing its performance and improving its safety. But they are also pursuing other approaches, such as solid-state batteries with ceramic ion conductors and various types of metal-air batteries. Together with the Central Institute of Engineering, Electronics and Analytics (ZEA), researchers from the Institute of Energy and Climate Research (IEK) are developing and optimising a range of battery concepts for different areas of application.

The research conducted focuses on material concepts, process engineering and process design for batteries. Energy density, resource efficiency, size, battery life and production costs must all be reconciled, and disposal aspects considered. In addition, researchers are also looking into the integration of current battery approaches into different sectors of the changing energy industry. The Helmholtz Institute Münster focuses specifically on research into electrolytes for internal ion transport between the two electrodes, including ceramic materials that prevent batteries from leaking or overheating.
