Time resolution of operando SXDM technique allows to image the dynamics of lattice evolution in sufficient detail at low C-rates. Figures show two scans corresponding to the Li 1 - side of Figures and, respectively. The spatial separation of these domains is clearly seen on the real-space tilt maps (Figure ) as they are presented in different colors that correspond to various local lattice orientations. The maximum angular deviation between two of the domains reaches 0.4 • . Indeed the shape of the Bragg reflection in Figure indicates that the tilting of the different domains of the particle proceeds as a result of the phase transformation. One can see a weak intensity distribution between the Li 1 peak below and each of the three Li 0.5 sub-peaks which indicates an intermediary transforming phase. The two Bragg reflections on the sides are connected with the Li 1 peak with diagonal traces indicating a tilt boundary between two phases with different Li concentrations similar to the case of LFP observed in Ref. . The central peak of the Li 0.5 phase however undergoes only a slight rotation along Q x (i.e. the beam direction) during the conversion. Interestingly, as the transformation continues the tilt boundaries disappear and the particle recrystallizes by realigning the tilted domains. The original contour of the particle is restored (dashed black line in Figure ) indicating a fully transformed recrystallized particle. Notably even at the scan 17 (see Figure ) after the dynamics of lattice orientation stabilizes, a map configuration is formed which highly resembles the three domain distribution observed later at the scan 19. Thus the "blueprint" of the metastable domain structure observed after transformation is formed in the crystal even before angular trifurcation happens at the end of the phase transition.
