Digital‐Twin‐Driven Diagnostics of Crack Propagation in a Single LiNi0.7Mn0.15Co0.15O2 Secondary Particle during Lithium Intercalation (Adv. Energy Mater. 23/2023)

Abstract

Crack Formation Diagnosis In article number 2204328 by Sung-Soo Kim, Yong Min Lee, and co-workers, a single few-micrometer-sized LiNi0.7Mn0.15Co0.15O2 particle is digital-twinned using FIB/SEM. The particle's electrochemical and mechanical properties are obtained through single particle measurement, nanoindentation, and axis lattice parameters. The digital-twin-driven electrochemo-mechanical model is developed using the digitaltwin structure and parameters. This model performs digital-twin operando analysis of electrochemical and mechanical properties. Finally, this advanced analysis allows the diagnosis of crack propagation.
