Applications: Solid state electrolyte material for all solid state lithium ion batteries. Tantalum doped LLZO, with nominal composition Li_6.4La₃Zr_1.4Ta_0.6O₁₂ (Ta-doped LLZO), is used as a solid electrolyte material for Li-based batteries because of its high Lithium ionic conductivity and chemical stability with respect to lithium as well as its stability at elevated temperatures. Because of its better electrochemical stability, LLZO is preferred than LLTO as a solid electrolyte material.
