a, b Cross-section SEM images of the LMO electrode in its fresh, uncycled state. Scale bars are 25 µm for (a) and 5 µm for (b). c, d Cross-sections of particles that were cycled 150 times, showing cracks propagating from internal pores (white arrows). Scale bars are 2.5 µm for (c) and 1.5 µm for (d). e Illustration showing the design of the operando micro-cell with magnified X-ray CT reconstruction. f Discharge voltage and current profile showing periods during which XRD-CT scans were carried out (blue). The XRD-CT periods are labeled 1–5 for future reference. g Integrated diffraction profiles from the first point measurement during each of the 5 XRD-CT scans with characteristic profiles from LiMn2O4 and Al for comparison.
