Understanding the solvation structures of electrolytes is important for developing nonaqueous redox flow batteries that hold considerable potential for future large scale energy storage systems. The utilization of an emerging ionic-derivative ferrocene compounds, ferrocenylmethyl dimethyl ethyl ammonium bis (triflyoromethanesulfonyl)imide (Fc1N112-TFSI), has recently overcome the issue of solubility in the supporting electrolyte. In this work, 13C1H and 17O NMR investigations were carried out using solvent. It was observed that the spectra of 13C experience changes of chemical shifts while those of 17O undergo line width broadening, indicating interactions between solute and solvent molecules
