Understanding the structural origin of the competition between oxygen 2. and transition-metal 3. orbitals in oxygen-redox(OR)layered oxides is eminently desirable for exploring reversible and high-energy-density li/Na-ion ***,we reveal the correlation between cationic ordering transition and OR degradation in ribbon-ordered P3.Na_(0.6)li_(0.2.Mn_(0.8)O_(2. via in situ structural *** two different voltage windows,the OR capacity can be improved approximately twofold when suppressing the in-plane cationic ordering *** find that the intralayer cationic migration is promoted by electrochemical reduction from Mn^(4+)to Jahn–Teller Mn^(3.)and the concomitant NaO_(6) stacking transformation from triangular prisms to octahedra,resulting in the loss of ribbon ordering and electrochemical ***-principles calculations reveal that Mn^(4+)/Mn^(3.)charge ordering and alignment of the degenerate eg orbital induce lattice-level collective Jahn–Teller distortion,which favors intralayer Mn-ion migration and thereby accelerates OR *** findings unravel the relationship between in-plane cationic ordering and OR reversibility and highlight the importance of superstructure protection for the rational design of reversible OR-active layered oxide cathodes.
