Excluding the phase-contrast element surrounding the particle edges, continued crack formation was observed up to 4.3 V, followed by a curious recovery at 4.4 V (see Figure , squares). At these higher states of delithiation (4.4 V), most primary particles lose a significant proportion of their lithium content, leading to lattice collapse. Consequently, lithiation states among primary particles may become more homogenous, slightly reducing apparent cracking and expansion. This contrasts with states of charge in the range of 4.2-4.3 V, where a continuum of lithiation states likely exacerbates heterogeneous volume changes in primary particles.
