The electrode was then imaged for a second time (after disassembly of the coin cell) and the same RoI was located to directly observe any changes induced by charging (delithiation) of the NMC particles. As shown in figure , and e, particles that have cracked show a lower attenuation of the X-ray beam in the regions where the cracks propagate, due to the lower density/lack of material. Since we are tracking individual particles, statistical errors introduced using bulk measurements, where the same particle cannot be examined before and after operation, have been mitigated. In all assessed particles, there was no cracking present prior to charging; consequently, we propose that the crack feature formations were introduced by the electrochemical charging conducted. To the authors' knowledge, this is the first temporally resolved imaging of the same particles that has been achieved using laboratory nano-CT, before and after electrochemical control. Here we have proven that it is possible to image and re-image the same particles without destroying the sample whilst retaining a commercially relevant environment. We propose that the existence of cracking within particles located in the tab region is a reasonable indicator that the tab in electrochemically active and participating in the overall electrochemistry of the cell, providing evidence that this set up can be a suitable proxy for larger format and commercial cells. ) Volume rendering of merged electrode showing the particle location of particle 1 to 8 in orange. j-q) Surface rendering of charged particle with volume rendering of the segmented cracking within (yellow). i-vii) Pristine particle centre ortho slice. 1-8) Charged particle centre ortho slice.
