Microstructure Reconstruction in Battery Electrodes Using Machine Learning Based on Low‐Voltage Focused Ion Beam–Scanning Electron Microscopy Tomography Images

Advanced Engineering Materials, EarlyView.
Low‐voltage FIB‐SEM tomography combined with a image preprocessing pipeline improves phase contrast and enables reliable machine‐learning segmentation of conductive networks in lithium‐ion battery electrodes. Structural descriptors are extracted from segmented images, done semimanually and automated, and compared.

An investigation into the morphology and crystallization process of lithium borate glass containing vanadium oxide

Journal of Materials Research and Technology, 2022
A series of lithium borate glasses with V2O5 were successfully prepared by melt annealing. The glass-ceramics were made by heating the glass to the glass transition temperature (Tg), then heating it to the crystallization temperature (Tc), converting it ...
