Li${}_{7}$La${}_{3}$Zr${}_{2}$O${}_{12}$ (LLZO), lithium lanthanum zirconate is a promising garnet-type solid electrolyte that is being intensively studied for solid-state lithium batteries. The properties of LLZO such as compatibility with the lithium electrode, stability, and ionic conductivity make them to be used in all solid-state batteries. Moreover, lithium ion concentration and distribution, doping different cations, chemical composition, and interaction between different dopants have remarkable effects on the ionic conduction of LLZO material. Herein, we investigate the solid electrolyte, Li${}_{6.4}$(Ga${}_{(1-y)}$In${}_{(y)}$)${}_{0.2}$La${}_{3}$Zr${}_{2}$O${}_{12}$ (y = 0.05, 0.10, 0.15, 0.20), by probing the influence of indium substitution to gallium sites at the same lithium concentration on the …
