Lithium-ion batteries

Ceramic materials and technologies are essential components of today’s lithium-ion batteries and will continue to play a key role in the future. At Fraunhofer IKTS, development work is aimed at the pilot scale to ensure a fast transfer of the results from fundamental laboratory research to industrial process development.

Fraunhofer IKTS applies its ceramics expertise towards synthesizing and preparing active materials and separator components, and processing them to form battery electrodes. A variety of methods is available for characterization of the electrode structure, electrochemical behavior, and aging during battery operation. As a result, a thorough understanding of the relationship between production conditions and battery reliability has been gained.

Decades of know-how in development of ceramic materials and technologies as well as in materials analysis and  electrochemical characterization ensure that new cost-effective strategies can be established. This involves materials, process, and systems development as well as supply of groundbreaking cell concepts for mobile and stationary applications.
