Source figures may contain other techniques and soft X-ray spectra. C, N and O measurements are outside our current hard-XAFS testing range.
FIGURE 4 Charge compensation and electronic structure analysis. Ex situ XANES spectra at Ni (a), Fe (b), and Mn (c) K-edges for pristine, charged (4.0 V), and discharged (2.0 V) states, with reference compounds. (d–f) Corresponding Fourier-transformed EXAFS spectra. Calculated total density of states (TDOS) for (g) NFM and (h) HEO. Calculated projected density of states (PDOS) for (j) NFM and (k) HEO. (i) Schematic illustration of Na+ migration pathway. (l) Migration energy barrier calculations for Na+ diffusion.
