Fig. 3. (a) The 1H NMR spectra of the –CH3 (TEP) of solvents with and without diluents and of the electrolyte with and without diluents. Raman spectra of the states of (b) P–O–C (TEP) and (c) S O (FSI−) in the different electrolytes. The percentages for free TEP and solvated TEP contents (d) and the percentages for free FSI−, CIP and AGG contents (e) in different electrolytes.
