Interactions between propylene carbonate (PC) and lithium bis(trifluoromethane sulfone imide) [LiTFSI, LiN(CF 3 SO 2 ) 2 ] were studied by Fourier transform (FT) Raman and IR spectroscopy. It was found that PC interacts with the Li + ions and the TFSI − anions through its skeletal oxygen atoms, leading to solvent‐separated ion pairs and contact ion pairs in the solution by way of the nitrogen atoms on the anion.
