Operando total scattering data of Li4Mn2O5:C composites. (a) Electrochemical performance (solid line) overlaid with refined lattice parameters (empty circles). PDF data were recorded during cycling. (b) PDF and (c) S(Q) functions at selected times [indicated by dashed lines in (a)] overlaid with the signal from carbon. The asterisks highlight diffuse scattering attributed to the in situ formation of a short-range-ordered superstructure. |
