Comparison of large-volume 3D reconstruction using plasma FIB-SEM and X-ray CT.

We demonstrated large-volume three-dimensional (3D) reconstruction using plasma-focused ion beam-scanning electron microscopy (PFIB-SEM). We successfully reconstructed a 750 µm (W) × 143 µm (H) × 310 µm (D) volume at a resolution of 200 nm/pix from 1550 SEM backscattered electron images of a Li-ion battery cathode sheet. The PFIB-SEM system was found to be capable of acquiring and reconstructing larger volume 3D datasets than X-ray computed tomography, and with higher resolution and contrast.
