Figure Lengend Snippet: Example of an operando depth profile measurement obtained with the BLiX CMXRF spectrometer. a) CMXRF spectra at three selected depth positions: at the HOPG window, in the NMC cathode and in the Cu back contact. b) 2D map of the CMXRF spectra in the energetic region between the Ar K and Cu K fluorescence lines as a function of relative depth (intensity is given in cps). c) Depth profiles of the individual fluorescence peaks are the net peak intensities as a function of relative depth. The different layers of the NMC coin cell are attributed to the elemental signals.
