Fraunhofer Institute for Material and Beam Technology IWS
Electrical energy storage systems are indispensable for a reliable and sustainable energy supply. As energy transition progresses, batteries are required both as mobile and stationary energy storage devices – for example, for electromobility or to compensate for fluctuating electricity production from renewable energies. The energy and environmental sectors as well as the automotive industry are therefore intensively involved in this topic.
At Fraunhofer IWS we are working on next generation batteries. In addition to lithium-ion technology, we focus on lithium-sulfur and solid-state battery concepts. Our key issues are energy density, range, charging time, weight and size as well as environmental compatibility and safety. In its function as energy carrier, hydrogen will also contribute decisively. With our expertise in materials and laser technology, we are developing innovative and economical solutions for storing and transporting hydrogen. Examples include magnetic pulsed-welded hydrogen pressure tanks and the production of metallic bipolar plates using roll-to-roll processes. In line with the "Green Economy" approach, we develop novel processes for the use of process heat as energy carrier and thus contribute to a better environmental balance for our customers.
