First-principle calculations suggest that transition-metal centres with non-bonding electronic configurations, cation disordering, redox-inactive species, isotropic structures, and octahedral-to-tetrahedral migration of Li can effectively minimize volume changes upon (dis)charging [100]. For instance, the introduction of compositionally complex dopants (Ti, Mg, Nb, and Mo) to Ni-rich layered cathodes or the incorporation of a coherent perovskite phase into the layered structure demonstrates a marked reduction in lattice dimension changes over a wide electrochemical window . This approach effectively mitigates the structural degradation through a pinning effect. Furthermore, eliminating synthesis-induced crystal defects, such as low-angle tilt boundaries, anti-phase boundaries, stacking faults, and dislocations, contributes to superior structural stability at high voltages while preventing irreversible oxygen release .
