Transmission electron microscopy (TEM) analysis indicates the coexistence of three 120° monoclinic twinning variants in the Li1.07Mn1.93O4−δ cathode materials. A theoretical investigation of the influence of stacking disorder on the X-ray diffraction (XRD) patterns was performed by employing the DIFFaX program and may help to clarify the ambiguity between experimental TEM and XRD investigations.
