Title

Neutron scattering investigation of charged polymers dynamics for application in redox flow batteries for energy storage

Abstract

The integration of storage capacities in the existing electrical grid system substantially 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 connected to their viscosity and, in turn, to diffusion processes at nanoscale. Here we propose to investigate nanoscale relaxation dynamics of two organic copolymers, which are promising candidates for highly efficient organic electrolytes in RFBs applications. We will investigate relaxation dynamics of the samples, when their structure will be systematically (ex-situ) charged, simulating the charging / discharging process in RFBs, when the charge of the redox moiety changes. The results of the study will provide an insight into microscopic mechanism of the transport processes and charge transfer, which can potentially enable the improvement and further optimization of materials for RFB applications.
