At Fraunhofer IWS, an interdisciplinary team is working on solutions for the battery of tomorrow – from the material to the cell.

With material and process innovations, we develop solutions for sustainable and high-performance battery cells. For example, the new DRYtraec® process eliminates the need for conventional solvents and energy-intensive drying steps in electrode production.

For the production of lithium metal batteries, we offer efficient process solutions from the manufacture of thin lithium layers to the automated assembly of the cells. Material science on structure-property relationships is the basis for holistic development of lithium-ion, lithium-sulfur and solid-state battery cells.

We have modern and extensive equipment at our disposal for battery research.

Our range of services includes:

  • Electrochemical characterization of battery materials and correlation with structural properties
  • Process innovations for electrode and battery cell manufacturing
  • Design and evaluation of battery cells
