| Abstract Scope |
Lithium lanthanum zirconate (LLZO) garnet is a promising solid electrolyte for future lithium batteries owing to its high ionic conductivity, compatibility with metallic lithium, and thermal stability. Our recently established molten salt synthesis (MSS) to obtain LLZO nanoparticles has numerous advantages over conventional solid-state reaction. Molten salts present a large design space wherein the properties of the melt can be tuned to vary the properties of the LLZO. Further, modifying the basicity of the salt melt can substantially reduce the formation temperature of LLZO. However, the increased complexity of chemistry in molten salts requires fine tuning of both the molten salt medium and precursors to obtain pure phase LLZO materials with good ionic conductivity. The effect of salt composition on the product distribution and particle size and morphology will be discussed. Further, the sintering properties and ionic conductivity characteristics of powders made from MSS will be presented. |
