LLZO Lithium Lanthanum Zirconium Oxide Material

Overview

LLZO (Lithium Lanthanum Zirconium Oxide, Li₇La₃Zr₂O₁₂) is a high-performance lithium-ion conducting ceramic widely studied for next-generation solid-state battery research. This garnet-type oxide exhibits fast lithium-ion transport through its three-dimensional crystal lattice, making it a benchmark material for investigating solid electrolytes and interfacial electrochemistry in advanced energy storage systems.

The cubic phase of LLZO is particularly valued due to its enhanced ionic conductivity and improved stability against lithium metal, compared to conventional liquid electrolytes.
