APPES data for composition analysis of 1 M LiTFSI in PC electrolyte. C 1s (a), F 1s (b), O 1s (c), N 1s (d), S 2p (e), and Li 1s (f) spectra of the Elect-Drop sample (1 M LiTFSI electrolyte on Li metal). The shaded areas represent the respective TFSI contributions in case of overlapping signals. The roman numerals indicate different measurement spots. The molecular formula of LiTFSI is shown in (g)
