a Region of interest selected for sampling using FIB–SEM, followed by stacking of the obtained 2D images. Corresponding b four-phase segmentation results and reconstructed 3D images of the cathode composite having 28.28 × 39.08 × 55.82 µm3 volume for c bare NCM and d) LiDFP NCM. Representative images of identification and quantitative information for e labeled cathode, f contact loss area, and g labeled pore. All the ASSB pellets were precycled in the range of 1.88–3.88 V (vs. In/InLi) under C/10 (1 C = 1.36 mA/cm2) at 25 °C with a stack pressure of 13 MPa.
