The ellipticity, sphericity and roundness for the four enclosed particles in Figure (#6,#2,#1 and #7) as well as the median values obtained from the analysis of the entire population are summarized in Table . The particle #2 has a very high roundness for a low sphericity value, typical of an elongated ellipsoid morphology, compared to particle #1, which has the roundness of a square and the sphericity of a triangle. Globally, most of the particles have a geometry in between the ones of particle #6 and #2 as highlighted on the graph of Fig. , whereas particle #1 belongs to the faceted-shape minority. The same trend is observed on smaller particles, as highlighted by the example of particle #7, with both large roundness and sphericity factor. Moreover, it is noticeable that the sphericity of particles decreases as their equivalent diameters increase, while keeping a high roundness factor (R ≥ 0.6 ). These particle morphologies likely reflect the growth process of large NMC crystals through coalescence, and not growth kinetics along different crystallographic directions.
