Mobile Energy Storage Systems and Electrochemistry


The Fraunhofer IKTS competences in electrochemistry and mobile electrochemical storage are combined in this department.

Its activities include the development of a large variety of electrochemical methods for the deposition of functional layers, the investigation of corrosion processes, and electrochemical machining (ECM). Electrochemical energy storage is one major application; others include microelectronics, photovoltaics, etc.

Lithium-ion technology is the primary focus in the development of mobile energy storage solutions. The manufacturing of such batteries requires new processes and an understanding of the value chain. The Battery Technology Application Center is able to cover the complete value chain for energy storage devices, including the development, manufacture and production of energy storage devices, in cooperation with IKTS working groups focused on materials engineering and technology. One focus is the description of the operational, error and long-term behavior of batteries.

The department develops new concepts, manufacturing processes and characterization methods for bipolar batteries (EMBATT) and new Li-ion battery generations.
