<u><b>3D data on an 18650 Li-ion Battery Nickel-Rich NMC811 Cathode</b></u><br> <br><div>Collected using an 810 Ultra X-ray-CT instrument (Zeiss Xradia 810 Ultra, Carl Zeiss., CA, USA).</div><div><br></div><div>Accelerating tube voltage of 35 kVp that employs a rotating chromium anode. <br></div><div><br></div><div>Quasi-monochromatic beam with a characteristic emission peak of 5.4 keV (Cr-Kα).</div><div><br> </div>A
capillary condenser produces focused X-rays for a full-field
illumination of the sample, projected onto the scintillator detector
using a Fresnel zone plate. <br><br><div>In order to capture the full electrode thicknesses, two CT scans were conducted of the sample.</div><div><br> </div>The two Zernike phase-contrast nano-CT scans of the cathode required 1200 X-ray radiograph projections per scan, with a 30 second exposure time per projection. <br><div><br></div><div>The raw radiographs can be made available upon request - please state 'EIL-011.tif' and 'EIL-012.tif'.</div><div><br> </div>The
two nano-CT datasets were then reconstructed using commercial software
employing parallel-beam filtered back-projection algorithms
(‘Reconstructor Scout-and-Scan’, Carl Zeiss., CA, U.S.A.),producing an
isotropic voxel length of 63.1 nm.<div><br> </div>The reconstructed
volumes were then stitched using Avizo Fire software (Avizo, Thermo
Fisher Scientific, Waltham, Massachusetts, U.S.A.) producing one nano-CT
tomogram (EIL-014.tif).<br><br><br>
