P1 - Self-healing electrodes for electro(chemical) energy storage

聚合物的自愈合是近年来研究的热点。在这样做的过程中，可以建立通用的设计原则，从而能够制备可治愈的聚合物。作为该项目的一部分，这些概念现在将被转移到功能材料上。具体地说，将开发用于有机基电池或(超级)电容器的新型电极，其特点是具有自我愈合的能力。为此，将具有各种可逆基团的自修复聚合物集成到电极材料中，以最终使裂纹和损伤得以愈合。除了合成，还将重点放在材料的表征上，特别是自愈性能的研究上。一方面，将对电极中的裂纹进行光学和触觉检查，另一方面，将分析功能特性的恢复，如导电性或容量。特别是，将建立一种新的方法，用于对功能材料的愈合进行详细的量化。最后，该项目旨在设计用于有机基电池和超级电容器的新的自愈电极，并阐明自愈功能材料的结构-性能关系。

The self-healing of polymers has been studied intensively in recent years. In doing so, general design principles could be established enabling the preparation of healable polymers. As part of the project, these concepts are now to be transferred to functional materials. Specifically, new types of electrodes for use in organic radical batteries or (super)capacitors are to be developed, which are characterized by their ability to heal themselves. For this purpose, self-healing polymers with various reversible groups are integrated into the electrode materials in order to ultimately enable cracks and damage to be healed. In addition to the synthesis, a focus will be on the characterization of the materials and, in particular, on the investigation of the self-healing properties. On the one hand, the cracks in the electrodes will be examined optically and tactilely, on the other hand, the restoration of functional properties, such as conductivity or capacity, will be analyzed. In particular, a new method will be established with which the healing of functional materials can be quantified in detail. Finally, the project aims to design new self-healing electrodes for applications in organic radical batteries and supercapacitors and to elucidate structure-property relationships for self-healing functional materials.
