Material Research

The member institutes of the Fraunhofer Battery Alliance develop, optimize and characterize tailor-made materials and components for next-generation battery systems. The focus is on the synthesis, modification and structuring of active materials, the development and optimization of separators and electrolytes and their comprehensive characterization. Material research and development work aims to increase tolerance to environmental influences, improve storage properties and increase intrinsic safety. The work centers on lithium-based cell chemistries such as lithium-ion, lithium-sulfur and solid-state batteries. Sodium-based batteries (sodium-ion batteries and high-temperature storage batteries), redox-flow batteries, metal-air batteries and alternative battery chemistries are also under research.
