Figure 10. (A) Illustration of ODH and TSH types of Li⁺ diffusion pathways^[106]. (B) Schematic diagram of Li⁺ distributions around tetrahedral sites in the cation-disordered oxide: 0-TM; 1-TM; 2-TM; 3-TM^[108]. (C) Illustration of a TMO₆ octahedron with two face-sharing tetrahedral sites. Migration of the TM from the octahedron transforms a 1-TM channel into a 0-TM channel^[109]. (D) D_Li⁺ of a LRMO material under different states during the initial charge^[110]. (E) Nyquist plots of Li_1.2Mn_0.56Ni_0.16Co_0.08O₂ electrodes at various potentials^[111]. (F) dQ/dV curve of O2-LRMO measured at a current density of 5 mA g^-1, which proves the reaction mechanism of anions at high potential^[98]. (G) Variation of discharge capacity as a function of current density is estimated for the two classified voltage ranges of 2.0-3.4 and 3.4-4.8 V^[98]. (H) Schematic diagrams of density of states at different states of charge (top) and anionic oxygen oxidation coupled with cationic reduction (bottom), showing the effect of different activation energy in the intermediate states on anionic kinetics in Li_1.2Ru_0.4Co_0.4O₂^[112]. ODH: Oxygen dumbbell hopping; TSH: tetrahedral site hopping.
