Alignment and analysis of operando XANES imaging of an NCM battery cathode upon charging. (a) Raw TXM images. (b) The results of ROI detection by Cycle-GAN. (c) The results of particle segmentation. (d) The results of XANES map reconstruction for the identified particles. (e) The Ni oxidation maps over the segmented and tracked particles at the end of the charging process, and their relative spatial offsets. |
