Abstract Scope |
Robust Li-ion batteries with enhanced energy and power density rely on coupling metal anodes with solid electrolytes that hinder dendritic growth through mechanical suppression. Solid electrolytes can be broadly categorized into polymer, and inorganic solid electrolytes exhibiting differing kinetics, transport, mechanics and microstructure characteristics with strongly coupled interactions. While the transport behavior of polymer electrolytes is similar to liquid electrolytes enabling ion motion through migration and diffusion, inorganic electrolytes only exhibit migration based ionic flux. Solid electrolytes also exhibit microstructural stochasticity (polycrystalline/amorphous with/without voids) which directly impact the transport, kinetics and mechanics behavior. Furthermore, the metal-solid electrolyte interfacial perturbation, dependent on the mechanical and chemical wettability, correlates to ion-flux focusing and electrodeposition hotspots. In this work, we investigate these coupled interactions and delineate electrodeposition stability for polymer and inorganic solid electrolytes based all-solid-state batteries. |
