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 Verification of the structural stability mechanism: (a) XANES and (b) R space of EXAFS spectra of LFP and RLFP. (c,d) Wavelettransform EXAFS results. (e) Raman spectra. (f) DOS of Na-RLFP. (g,h) The comparison of Fe─O/P─O bond length between LFP and Na-RLFP. (i–k) The XRD and XPS of RLFP and Na-RLFP after cycling. (l,m) Schematic of structural changes in RLFP and Na-RLFP after cycling.
