Applied Electrochemistry

Batteries, fuel cells, electrochemical sensors and analysis systems are the main research topics in the Applied Electrochemistry Department. Research and development work for both the civil and the defense sector ranges from material characterization and optimization to the development of methods and the production of prototypes. Comprehensive testing and development methods for fuel cells, batteries and components are developed and offered as part of our service.

Research areas in the Applied Electrochemistry Department




The research group working on batteries has over 35 years of experience with electrochemical energy storage devices for civil and defense applications. Work focuses on lithium ion systems on a cell and modular level, and double-layer capacitors.



Fuel cells

Fuel cells are characterized by high efficiency, low noise, low emission of pollutants and high energy storage density. The Department AE has extensive expertise in electrochemical processes in fuel cells, as well as the equipment needed to carry out every conventional test on fuel cells and their components. Additional research topics include energy systems for military applications and hybrid battery / fuel cell systems.


Redox-flow batteries

Redox-flow batteries are more efficient than conventional batteries and have a significantly longer service life. The storage concept allows the power output to be up-scaled independently of the capacity. The battery can therefore be tailored to any application.


Sensors and analytical systems


We offer customer-specific development of sensors, analytical methods and pattern recognition based on electrochemical methods. We also develop methods and systems to measure low concentrations of substances in the air, soil and water.



Project »RedoxWind«

Energy storage devices are becoming increasingly important as a result of the German energy transition. They can compensate for natural fluctuations in solar and wind energy, and thus convert a renewable energy source into a predictable generating station with uninterrupted supply. They can also make a decisive contribution to grid stability and frequency control, and reduce the need to extend the grid.
