a The optimized structures of nLCO2.5 phase. b Schematic diagram of Co 3d orbits splitting in [Co1–O5] and [Co2–O5] tetragonal pyramid, including the low spin of Co1 and high-spin of Co2. c Projected density of states of Co1, Co1′, and Co2. d Integrated spin as a function of the radius around Co1, Co1′, Co2, La, and O ions. e Projected density of states of nLCO2.5 structure.
