Charge induced conformational changes in organic electrolytes for applications energy storage devices.
The integration of storage capacities in the existing electrical grid system sub¬stantially enhances its efficiency even with existing generation assets. The major challenge here is the development of durable and low cost solutions for energy storage, e.g., redox flow batteries (RFBs), whose development is attracting a lot of attention today. The performance of RFBs depends, to large extend, on the performance of electrolytes, which is closely dependent on their structure. Here we propose to investigate charge induced conformational changes of two organic copolymers, which are promising candidates for highly efficient aqueous electrolytes in RFBs applications. We will investigate structure and gyration radius of the samples, when the polymers will be systematically in-situ charged, simulating the charging / discharging process in RFBs, when the charge of the redox moiety changes. Since the structure determines the viscosity behavior of the electrolytes and, hence, a charge transport, the results of the study will provide a fundamental understanding of the charge transfer at the nanoscale and a basis for optimization of the molecular structure of the materials.
