During discharge the tilt domains that were formed in the course of the transformations are visible on the misorientation maps throughout the whole process. The evolution of the lattice during the phase transitions is noticeably different with a formation of more heterogeneous tilt structure however with similar lattice misorientation variation. The difference between the lattice transformation mechanisms between charge and discharge is likely due to inverse ar-Figure : Comparison of tilt maps and pole plot of the particle in the beginning of charging (A), during the Li 1 -Li 0.5 transition and after the full discharge (C). Lines on the maps represent the boundaries of the three domains observed (yellow lines on Figure ). Values on the top right of the pole plots represent the upper limit for the altitude (radial) axis of spherical coordinates. rangement of phases in the discharge process compared to the charge. In this case the phase with bigger lattice constant is located on the surface while regions with lower lattice constant is located in depth of a particle. The three domain structure of the particle can be traced right until the full discharge of the particle (Supplementary Videos 4-6). In Figure it is compared to the maps of the particle during the charge phase transition (B) and in the beginning of the cycle (A). While the maximum angular deviation before and after the cycle are comparable (0.05 • and 0.06 • ), the posi-tions of the tilt boundaries after the discharge closely resembles the one observed during the phase transition. This suggests an irreversible change of crystal structure throughout cycling due to the lattice orientation observed during the phase transitions.
