Neutron scattering investigation of charged polymers dynamics for application in redox flow batteries for energy storage
The major challenge in the integration of storage capacities in the existing electrical grid system is the development of durable and low cost solutions for energy storage, e.g. redox flow batteries (RFBs). The performance of RFBs depends to large extend on the charge transfer in electrolytes, connected to their viscosity and to diffusion/ relaxation processes at nanoscale. Here we propose to investigate nanoscale relaxation dynamics of organic copolymers, who are promising candidates for highly efficient organic electrolytes in RFBs applications. In our first study of cationic comonomer, whose structure consists from periodically distributed cation units, we observed charge-induced changes originating from the change of the polymer chains shapes and increased chains interactions. Now we would like to extend this study to zwitterionic polymers whose structure consists of oppositely charged cationic and anionic groups along the side chain with attractive and repulsive interactions. Beside the industrial interest, this gives an opportunity of the systematic study of cooperative ionic interaction and provide a fundamental understanding of the charge transfer at the nanoscale.
