Multi‐Physical Field Simulation: A Powerful Tool for Accelerating Exploration of High‐Energy‐Density Rechargeable Lithium Batteries

Abstract To meet the booming demand of high‐energy‐density battery systems for modern power applications, various prototypes rechargeable batteries, especially lithium metal batteries with ultrahigh theoretical capacity, have been intensively explored, which are intimated new chemistries, novel materials and rationally designed configurations. What happens inside is associated interaction multi‐physical field, rather than result evolution a single physical such as concentration electric stress morphological evolution, etc. In this review, field simulation relatively wide length timescale focused formidable tool to deepen insight electrodeposition mechanism Li electro‐chemo‐mechanical failure solid‐state electrolytes based on Butler‐Volmer electrochemical kinetics solid mechanics, can promote future development state‐of‐the‐art satisfied energy density well lifespan.
