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 6. The charge compensation mechanism. (a–h) Ni and Mn K-edge XAS spectra and corresponding EXAFS spectra for NNMO and MAT- NNMO at different states, respectively. (i, j) The obtained oxidation state of Ni and Mn at different states. (k, l) Decoupled charge compensation mechanism along with the first charge–discharge process.
