The solid-state nature of all ASSB cell components, combined with the volume changes of the active materials during (de-)lithiation, introduces complex interplays between electrochemical, transport and mechanical processes, which strongly affect the overall cell performance . In LIBs, electrodes are typically designed as porous microstructures that allow the liquid electrolyte to infiltrate, ensuring significant wetting of the AM across all regions and enabling relatively short pathways for ion transport . However, the scenario changes in ASSBs as the inorganic SE is already integrated into the electrode during fabrication.
