Stationary Energy Storage Systems


© Fraunhofer IKTS
cerenergy® high-temperature battery for the stationary energy storage.

Electrical energy storage systems play an important role when sustainably shaping the future of the world’s energy supply. Most attention in this field is being given to sodium-based batteries, ceramic catalysts for metal-air batteries and ceramic alkali-ion conductors.

The department uses its know-how in materials science and technical manufacturing solutions to develop materials, manufacturing methods and innovative battery designs – always with an eye on applicability. For this purpose, Fraunhofer IKTS has highly modern plants and analytical equipment at its disposal, which are used for examining new cost-efficient processes and acquiring a deeper understanding of the operation and aging of battery storage solutions.
