Overcoming the Probing-Depth Dilemma in Spectroscopic Analyses of Batteries with Muon-Induced X-ray Emission (MIXE)

Datasets used in the publication "Overcoming the Probing-Depth Dilemma in Spectroscopic Analyses of Batteries with Muon-Induced X-ray Emission (MIXE)". fig_2: MIXE spectra of (a) an empty laminated Al pouch, (b) a Li metal foil in a laminated Al pouch, (c) a NMC622 electrode in a laminated Al pouch fig_3: MIXE spectrum of a NMC811 electrode in a laminated Al pouch, measured at 23.8 MeV/c fig_4b: Muon stopping profile simulated using PHITS for the cell geometry depicted in Figure 4a of the main manuscript fig_4c: Depth-resolved MIXE spectra of a NMC811||graphite Li-ion battery. Raw data at the 11 momenta measured, and table with the integrated peak areas for selected (K-L) lines. Update in version 2: raw datasets now have one energy column for each momentum. The datasets are of different lengths for each momentum and there was and error in copying the data in version 1. fig_4c: Table with calculated elemental ratios of the different transition metals (Ni, Mn and Co), at the momenta corresponding to implantation in the NMC811 electrode fig_s2: MIXE spectrum of a NMC622 electrode in a laminated Al pouch, measured at 23.0 MeV/c fig_s3: MIXE spectrum of a NMC111 electrode in a laminated Al pouch, measured at 22.8 MeV/c fig_s4_s5_simulations: Raw data of the muon implantation simulations for the NMC811/graphite cell Update in version 2: added fig_s4_s5_simulations file fig_s6: Labelled MIXE spectra (all peaks identified) of a NMC811 electrode in a laminated Al pouch, measured at 24.0, 26.0 and 28.0 MeV/c
