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 5. (a) Mn K-edge XANES spectra and (b) EXAFS spectra of P-LLO and G-LLO. (c) The wavelet transforms of Mn K-edge EXAFS of G- LLO. The first two charge−discharge profiles and in situ magnetic responses at 3 T of (d) P-LLO and (e) G-LLO. EPR spectra measured at (f) 2 K and (g) 65 K of both cathodes charged to 4.8 V. (h) Schematic illustration of the structure and molecular orbital diagram. The black arrow signifies an electron extracted from the O 2p orbital during charging.
