a XPS spectra of a pristine LPSCl surface on the left (in blue) and of an LPSCl surface that was in contact with LiLP CE during stripping on the right (in red). b ToF-SIMS depth profiles of a pristine LPSCl surface on the left and an LPSCl surface that was in contact with LiLP CE during stripping on the right. The intensity of the signals was normalized to the total counts. The LPSCl surface after deposition was analyzed ex-situ after stripping 12 mAh cm−2 of LiLP in a reservoir-free cell (see Fig. 1).
