Lithium-ion Battery INR18650 MJ1 3D X-ray CT Data: Graphite-Silicon Anode (EIL-013)

<b>3D data on an 18650 Li-ion Battery Graphite-Silicon Anode</b><b><br></b><br> <br>Collected using an 810 Ultra X-ray-CT instrument (Zeiss Xradia 810 Ultra, Carl Zeiss., CA, USA).<br>Accelerating tube voltage of 35 kVp that employs a rotating chromium anode. <br><br>Quasi-monochromatic beam with a characteristic emission peak of 5.4 keV (Cr-Kα).<br> 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>In order to capture the full electrode thicknesses, two CT scans were conducted of the sample.<br> The two absorption-contrast nano-CT scans of the anode required 2400 X-ray radiograph projections per scan, <br>with a 60 second exposure time per projection. <br><br>The raw radiographs can be made available upon request - please state 'EIL-009.tif' and 'EIL-010.tif'.<br> 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.<br> 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-013.tif).<br><br>
