In order to develop advanced organic radical batteries (ORBs), all components of these systems need to be carefully considered and developed. In the past years most of the research efforts on ORBs have been dedicated to the synthesis of novel active polymer materials, while the electrolyte has been only marginally considered. Nevertheless, the electrolyte represents a key component of ORBs, and it has been shown that a thoughtful selection and design of the electrolyte might significantly improve the electrochemical behavior of polymer-based electrodes. Presently, there is a lack of knowledge about the interactions occurring between the electrodes and electrolyte of ORBs, which is strongly hindering the development of these storage systems. To overcome this problem, a fundamental understanding of this interplay appears indispensable. Within the ElectroPoly project, the two PIs (Prof. Balducci and Prof. Schubert) want to address this fundamental aspect and want to gain novel insights into the impact of the electrolytes on the behavior of polymer-based electrodes via the combination of expertise in electrolytes and electrochemistry (Balducci group) as well as polymer synthesis and characterization (Schubert group). The objective of the project is the understanding of the influence of the electrolyte on the stability of modified TEMPO-based polymers in view of their use in organic radical batteries. We anticipate that the combination of electrochemical and spectroscopic techniques, which so far have not been used to investigate electrolytes of ORBs, will supply novel and precious information about this key component and its interplay with the electrode materials.

为了发展先进的有机自由基电池(ORBS)，需要仔细考虑和开发这些系统的所有组件。在过去的几年里，大多数关于球体的研究工作都致力于合成新型活性聚合物材料，而对电解液的研究还很少。然而，电解液是ORBS的关键成分，已有研究表明，精心选择和设计电解液可能会显著改善聚合物基电极的电化学行为。目前，对球体的电极和电解液之间的相互作用缺乏了解，这严重阻碍了这些存储系统的发展。要解决这一问题，对这种相互作用的基本理解似乎是必不可少的。在ElectrPoly项目中，两位PI(Balducci教授和Schubert教授)希望解决这一基本问题，并希望通过结合电解液和电化学(Balducci组)以及聚合物合成和表征(Schubert组)的专业知识，对电解质对聚合物电极行为的影响获得新的见解。该项目的目的是了解电解液对改性TEMPO基聚合物稳定性的影响，因为它们在有机自由基电池中的使用。我们预计，电化学和光谱技术的结合，将为这一关键成分及其与电极材料的相互作用提供新的和宝贵的信息。
