In this work, we demonstrate methods for quantifying the degradation of NMC particles, at both particle and sample levels, and at low and intermediate damage states. This was achieved in large micro-CT datasets of 10,000+ particle instances. The method assumes secondary particles with cracks will have observably lower greylevels with absorption contrast CT compared to an otherwise identical pristine particle, see figure . This is due to the 'partial volume effect' where voxels representative of space with both void and solid phases result in grey-levels that are intermediate between voxels representative of void or solid only, as previously described in Wade et al. . We show that although this grey-level change is small on the particle level (when averaged over a whole particle), when considered over a sample of thousands of particles, it is statistically significant. Hence, by tracking grey-level change we have a proxy for tracking cracking in particles.
