Contour plots of in situ XRD patterns and the corresponding crystal parameters evolution of (a, c) NFM, and (b, d) CFTS5 cathodes. Charge compensation mechanism in CFTS5 cathodes. Ex-situ XANES spectra and the corresponding EXAFS spectra at the (e, f) Mn, (g, i) Ni, and (h, j) Fe K-edges of CFTS5 at different charge/discharge states. DEMS data during the initial cycle of (k) NFM and (l) CFTS5 cathodes (active mass loading of ~10 mg cm−2).
