This collaborative research project of IPF Dresden and FSU Jena aims at the development of novel polymer electrolytes complementary to model active materials for polymer-based bat-teries. The electrolytes will be developed with tailor-made properties regarding ion transport, mor¬phology, thermal and electrochemical stability as well as compatibility to the electrodes (i.e. active material and conductive additive). The principle transport mechanisms will be studied, just as the influence of the electrolyte structure and interfaces on the cell performance. The main scientific aim of the project is to gain a better understanding of correlations between the chemical and morphological structure of the cell components with the performance of model polymer batteries. For this, in a first approach, polymeric single-ion conductors for anions will be synthesized, which are suitable electrolyte systems for active polymeric materials requiring anion-shuttling. The second approach aims at a charge transport reversal by equipping the active materials with charged species. These research activities will extended by developing triblock copolymer containing all necessary components for a molecular battery.
