12 MATERIAL DEVELOPMENT AND CHARACTERIZATION At the Fraunhofer Institute for Chemical Technology ICT, materials for redox-flow batteries are investiga- ted and further developed. This includes the characterization of battery materials, investigations into long-term stability and the development of corrosion-stable bipolar plates. An important challenge in the field of redox-flow batteries is to reduce the cost of the functional materials in the stack. In order to achieve a significant cost reduction while at the same time optimizing the electrochemistry of the system, Fraunhofer ICT continuously investigates new materials in terms of their potential for application in redox-flow batteries. For this purpose individual cells are set up and characterized using electrochemical methods (e.g. impedance spectroscopy and charge/discharge tests). In the cell test, materials such as membranes, porous and textile electrodes, materials for bipolar plates, alternative cell geometries and novel electrolyte formulations are tested regarding their performance and efficiency. Single cells can also be equipped with reference electrodes, so that the properties of the half-cells can be examined separately. In addition, various flow-through cells are used to conduct VIS/NIR and RAMAN spectroscopic in-situ measurements on electrolytes at different states of charge. Test cells for novel redox-flow battery systems have been developed and constructed at the institute since 2006. Bipolar plates play a decisive role as internal current collectors within redox-flow batteries. The development of cost-effective, mass-producible, electrically highly conductive and chemically stable bipolar plates made from carbon polymer composites is essential for the commercial breakthrough of redox-flow batteries. At Fraunhofer ICT materials can be produced from the compound to the finished plate or foil. Using injection molding, bipolar plates with dimensions of up to 800 x 250 x 3 mm can be produced.
