Fig. 3.
Partial densities of states with electrochemical charging in L(4-y)/3Mn1/3Nb1/3O2 as calculated with the DFT method. The calculated partial electron density is also shown. Li removal at y ≥ 1.0 indicates oxidation of oxide ions due to the formation of unoccupied oxygen p-states above the Fermi level (EFermi) as shown in the light blue circle in the magnification.
