“…performed electrochemo‐mechanical analysis on NCM/LGPS/LiIn and LCO/LGPS/LiIn configuration batteries by finite element analysis (FEA). [ 91 ] In this study, the authors simulated the stress distribution within the SSE caused by electrode volume changes and further mechanical damage behavior, including plastic deformation, interfacial debonding, and crack propagation. The simulation showed that the most severe mechanical damage to SSE occurred when cathode and anode active materials exhibited opposite volume changes (such as the NCM cathode shrinkage and the LiIn anode expansion during the charging process).…”

Sulfide‐based all‐solid‐state batteries (ASSBs) are one of the most promising energy storage devices due to their high energy density and good safety. However, due to the volume (stress) changes of the solid active materials during the charging and discharging process, the generation and evolution of electrochemomechanical stresses are becoming serious and unavoidable problems during the operation of all‐solid‐state batteries due to the lack of a liquid electrolyte to partially buffer the stress generated in the electrodes. To understand these electrochemo‐mechanical effects, including the origins and evolution of mechanical or internal stresses, it is necessary to develop some highly sensitive probing techniques to measure them precisely and bridge the relationship between the electrochemical reaction process and internal stress evolution. Herein, recent progress on uncovering the origins of the internal stresses, the working principle and experimental devices for stress measurement, and the application of those stress‐measuring techniques in the study of electrochemical reactions in sulfide‐based ASSBs are briefly summarized and overviewed. The investigation of precise and operando monitoring techniques and strategies for suppressing or relaxing these electrochemomechanical stresses will be an important direction in future solid‐state batteries.

“…Other SSEs such as Li 2 S-P 2 S 5 and LGPS systems present similar situations and results with LPSC electrolytes. 114,115 However, for LGPS electrolytes, the maximum stack pressure is generally much higher than Li 2 S-P 2 S 5 and LPSC electrolytes. When working at relatively high pressure, part of the distorted Li metal reacts with LGPS electrolyte promptly because of the particularly unstable thermodynamic interface between LGPS systems and Li metal, along with an increased overpotential.…”

The ionic conductivity of solid-state electrolytes at room temperature is crucial for commercializing lithium-ion batteries with solid-state electrolytes. Ab initio methods encounter a challenge due to their substantial computational resource demands. Classical molecular dynamics methods, on the other hand, are suitable for large-scale systems with simulation times reaching the nanosecond scale. However, they rely on empirical parameters in force fields, limiting their use to systems with well-established and extensively validated parameters, which is a constraint in studying new materials. A simulation approach combines ab initio simulations and classical molecular dynamics. Deepmd-kit, a deep learning tool, trains a tailored force field model using ab initio simulation data for the target system. However, as an approximate method, its reliability must be compared with ab initio results. As a data-sensitive method, the amount of data required to achieve the desired accuracy varies for different systems and must be tested accordingly. This paper performs convergence training for system size and simulation time concerning Li10GeP2S12 solid-state electrolytes, establishing the convergence criteria for deep learning data in this system.
