| Abstract Scope |
Development of solid electrolytes, along with the utilization of Li metal anodes can potentially enable rechargeable batteries with enhanced power density, energy density and safety. Achieving stable electrodeposition in solid-state batteries (SSBs) requires overcoming fundamental electro-chemo-mechanical, ion transport and interface stability challenges such as filament growth, mechanical failure and contact loss. In particular, microstructural arrangement of the solid electrolyte including grain boundaries and voids play a critical role in determining the morphological stability of the solid-solid interface. In this work, we present a mechanistic analysis of the ion transport response and electrochemical-mechanical interactions that dictate the propensity for metal penetration along grain boundaries in crystalline solid electrolytes. Based on the mesoscale analysis, key design strategies that can intrinsically modulate the stability of grain boundary-electrode junctions in SSB systems are discussed. |
