Abstract Lithium (Li) penetration into solid‐state electrolytes (SE) is a major cause of lithium‐metal battery (LMSSB) failure. However, no single model fully explains experimental phenomena, and many simulation‐based conclusions lack validation or contradict results, hindering the understanding failure mechanisms. This study integrates simulation data to investigate Li deposition SE cracking, introducing unified phase‐field (PF) model. Unlike existing models, it accounts for mechanical constraints, solid–solid contact, large‐strain mechano‐chemical coupling. It also distinguishes from as short‐circuiting cracking do not occur simultaneously. Additionally, crack initiation follows pressurized model, while propagation occurs through wedge‐shaped opening. A counterintuitive approach extending LMSSB lifespan reduce constraints rather than decreasing defect size increasing hardness toughness, provided that good contact maintained between electrode SE. because minimizing alters mode, preventing rapid eruption in cracks.

Abstract Solid‐state batteries (SSBs) have garnered significant attention as promising and safe electrochemical solutions for high‐energy storage. Despite their advantageous characteristics, the widespread adoption of SSBs encounters obstacles. Foremost among these challenges is inadequate solid‐state electrolyte (SSE)‐electrode contact, particularly under typical operating conditions with moderate pressures. Consequently, substantial external pressures are conventionally applied to establish a tightly bonded low‐impedance interfacial connection. Unfortunately, high pressure concurrently precipitates detrimental effects, such SSE structural fractures premature short circuits. Moreover, parameters that currently employed in laboratory‐scale research lack consistency far exceed current industrial requirement (< 1 MPa), which undermines objective evaluation SSBs’ actual performance hampers practical utilization.
