Figure 1. (A) Local coordination of oxygen with one Li-O-Li and two Li-O-M configurations and a schematic of the band structure for Li-rich layered oxides^[25]. (B) Schematic of π-type hybridization of the Li-O-Li axis with neighboring TM and the band structure for the π-type hybridized state of the Li-O-Li axis interacted with M t_2g^[27]. (c) Local coordination around Mn³⁺ and Mn⁴⁺ in LiMn₂O₄ (left) and λ-MnO₂ (right) obtained from theoretical calculations. The gray and red spheres represent Mn and oxygen atoms, respectively^[33].
