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

近年来，聚合物材料的自修复现象得到了广泛的研究。在这样做时，可以建立通用设计原则，从而能够制备可愈合的聚合物。作为项目的一部分，这些概念现在将被转移到功能材料。具体地，将开发用于有机自由基电池或（超级）电容器的新型电极，其特征在于它们的自我修复能力。为此，将具有各种可逆基团的自愈合聚合物整合到电极材料中，以最终使裂缝和损坏得以修复。除了合成，重点将是材料的表征，特别是对自愈性能的研究。一方面，将对电极中的裂纹进行光学和光学检查，另一方面，将分析功能特性的恢复，例如电导率或容量。特别是，将建立一种新的方法，与功能材料的愈合可以量化的细节。最后，该项目旨在设计用于有机自由基电池和超级电容器的新型自修复电极，并阐明自修复功能材料的结构-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.
