By using XRD measurements, it was established that, upon Li+ extraction, these cathode materials demonstrate structural transformations of the hexagonal phase (space group R‐3m) H1 to another hexagonal phase H2 (with a lower Li‐ion content in the lattice) and to domains comprising both of these two phases, coexisting at potentials E≈4.2–4.3 V.
