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.

IPF Dresden和FSU Jena的合作研究项目旨在开发新型聚合物电解质，以补充聚合物基电池的模型活性材料。电解液将在离子传输、形貌、热和电化学稳定性以及与电极（即活性材料和导电添加剂）的相容性方面具有量身定制的性能。主要的传输机制将被研究，正如电解质结构和界面对电池性能的影响。该项目的主要科学目标是更好地理解电池组件的化学和形态结构与模型聚合物电池性能之间的相关性。为此，在第一种方法中，将合成阴离子的聚合物单离子导体，这是需要阴离子穿梭的活性聚合物材料的合适电解质体系。第二种方法旨在通过给活性材料配备带电物质来实现电荷输运逆转。这些研究活动将通过开发包含分子电池所有必要成分的三嵌段共聚物来扩展。
