Stacking types that are considered as being apparent in the microstructure of the NCA-precursor materials; the bottom layers are indicated with yellow and the top layers with blue octahedra. (a) Brucite-type C6 stacking, (b) CdCl2-type C19 stacking, (c) CrOOH-type 3R stacking and (d) interstratification of water/carbonate. The coordinate systems refer to the transformed unit cells with a = b = 5.246 Å, c = 4.647 Å, α = β = 90° and γ = 120° (Fig. S1). The possible layer-to-layer transitions and the related stacking vectors are presented in Fig. 6.
