Digital-Twin Modeling and Simulations on All-Solid-State Batteries

Abstract

The use of digital twin technology for investigating all-solid-state batteries (ASSBs) has gained significant attention. Digital twin modeling is crucial in obtaining key design parameters such as effective ionic or electronic conductivity, specific contact area, which are difficult to obtain through experiments. This work presents two methods, bottom-up and top-down, for creating 3D microstructures of composite electrodes and discusses recent progress in upgrading both methods to uncover veiled parameters in ASSBs. Furthermore, the digital-twin electrode structures are coupled with electrochemical, thermal, and mechanical changes. This work is a valuable guideline for researchers working on ASSBs and related fields.
