Heteroaromatic redox polymers for lithium/organic batteries (HALO)

本研究的目标是设计和合成杂芳烃氧化还原聚合物作为锂/有机电池的阴极活性材料，并研究电荷稳定和存储的机理。初步研究表明，由于氧化还原活性基团之间的电荷稳定π-π相互作用，这种氧化还原聚合物在与快速充放电过程（10C下10,000次循环）相结合时具有高循环稳定性的潜力。研究将作为B. Esser, Freiburg（氧化还原聚合物的合成和（电化学）表征，π-π相互作用的机理研究）和M. Winter, m<s:1> nster（锂/有机电池电池中氧化还原聚合物复合电极的实现，电池级有机电极的制备和开发，电极设计的改进，电化学充放电过程的机理研究）小组的合作项目进行。该项目的一个重要部分将是对基于氧化还原聚合物电极的电化学充放电过程的机理研究，其结果将用于通过适应性分子设计和合成来改进氧化还原聚合物。最后，将设计和研究使用氧化还原聚合物作为阳极和阴极的全有机电池。

The goals of the proposed research are the design and synthesis of heteroaromatic redox polymers as cathode-active materials for lithium/organic batteries and the mechanistic investigations of charge stabilization and storage. Preliminary investigations have shown that such redox polymers have the potential for high cycling stabilities in combination with fast charge/discharge processes (10,000 cycles at 10C) due to charge-stabilizing π-π interactions between the redox-active groups. Research will be carried out as a collaborative project between the groups of B. Esser, Freiburg (synthesis and (electrochemical) characterization of redox polymers, mechanistic studies of π-π interactions) and M. Winter, Münster (implementation of redox polymer-based composite electrodes in lithium/organic battery cells, preparation and development of battery-cell-scale organic electrodes, improvement of electrode design, and mechanistic studies of electrochemical charge/discharge processes). An important part of the project will be the mechanistic investigations of the electrochemical charge/discharge processes in the redox polymer-based electrodes, the results of which will be used to improve the redox polymers through adapted molecular design and synthesis. Lastly, all-organic battery cells will be designed and investigated using redox polymers for the anode and cathode.
