Abstract Scope |
Solid-state batteries (SSBs) that utilize a lithium metal anode can potentially improve the energy density, power density and safety of lithium-ion batteries. However, achieving stable electrodeposition in SSBs continues to be a major challenge, dependent on various aspects such as electro-chemo-mechanics, transport and morphological evolution. Dynamic evolution of the lithium-solid electrolyte interface is governed by factors including the microstructure of the solid electrolyte and lithium metal, interfacial roughness, presence of defects/voids, and the external pressure and temperature. In this presentation, we study the role of microstructural heterogeneities (e.g., grain boundaries) and the competing nature of interfacial mechanisms on the electrochemical-mechanical response and failure onset in SSBs. The effect of electrodissolution, lithium diffusion and ionic transport interaction on the propensity for void formation in the metal anode and the resulting electrochemical performance is analyzed. |
