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

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

采用蔡司Xradia 810 Ultra型810 Ultra X射线计算机断层扫描仪（Zeiss Xradia 810 Ultra，卡尔蔡司公司，加利福尼亚州，美国）收集的18650型锂离子电池石墨硅阳极的3D数据。加速管电压为35千伏峰值，采用旋转式铬靶。准单色光束，具有5.4千电子伏特（Cr-Kα）的特征发射峰。毛细管聚光器产生聚焦的X射线，以全场照明方式照射样品，并通过菲涅耳区板投射到闪烁探测器。为了捕捉完整的电极厚度，对样品进行了两次CT扫描。每次扫描需要2400个X射线摄影投影，每个投影曝光时间为60秒。原始X射线照片可应要求提供，请指定文件名'EIL-009.tif'和'EIL-010.tif'。随后，使用商业软件（'Reconstructor Scout-and-Scan'，卡尔蔡司公司，加利福尼亚州，美国）通过并行束滤波反投影算法对两个纳米CT扫描的阳极进行了重建，生成各向同性的体素长度为63.1纳米的重建体积。然后，使用Avizo Fire软件（Avizo，赛默飞世尔科学公司，马萨诸塞州沃尔瑟姆，美国）将这些重建体积拼接成一张纳米CT断层扫描图（EIL-013.tif）。
