Our competences

The Fraunhofer Battery Alliance, consisting of 26 Fraunhofer institutes, researches in the field of electrochemical energy storage devices (batteries and super-capacitors) in order to develop technical and conceptual solutions for commercial applications. Particular consideration is given to the social, economic and ecological implications of the technology. The Battery Alliance will further develop and expand research in the field of electrochemical energy storage devices as a central business area of the Fraunhofer-Gesellschaft. The competences of the Fraunhofer Battery Alliance cover materials, cell production, systems, simulation and testing.

Materials

The Fraunhofer Battery Alliance develops, optimizes and characterizes customer-specific materials and manufacturing processes for batteries. Emphasis is placed on lithium-ion systems and double-layer capacitors.

Materials

Simulation

The Fraunhofer Battery Alliance uses cutting-edge techniques to simulate the properties of batteries from the atomic scale up to the behavior of the powertrain. Research is carried out on a variety of different topics.

Simulation

Cell Production

The further development of existing cell systems as well as the research on technologies of the future (lithium-air, lithium-sulfur, ...) are an essential working area of the Battery Alliance. The focus is on new materials and materials for the electrodes, new electrode systems and separators.

Cell Production

Testing

The testing and evaluation of energy storage devices is an important stage in the development chain for automotive applications. Due to the range of challenges involved a significant number of attributes must be investigated.

Testing

System

The lithium-polymer secondary battery system developed by the Fraunhofer Battery Alliance can be used to achieve specific requirement profiles. Starting with the development of foils, the manufacturing concept enables the manufacture of customer-specific secondary batteries in a wide range of formats.

System

End-of-Life und Batterierecycling

Batteries are a key factor for the implementation of the energy transition. To ensure a sustainable approach, a holistic view of battery technologies is necessary.
