LLZTO Lithium Lanthanum Zirconium Tantalum Oxide

Overview

LLZTO Cathode Active Material (Li₆.₇₅La₃Zr₁.₇₅Ta₀.₂₅O₁₂) Powder is a high-purity lithium lanthanum zirconium tantalum oxide with a cubic garnet crystal structure, widely used in advanced solid-state battery research. This material is engineered to deliver high lithium-ion conductivity, excellent chemical stability, and strong compatibility with lithium metal and oxide electrodes.

Principle and Material Behaviour

LLZTO belongs to the garnet-type lithium oxide family, where partial tantalum substitution stabilises the cubic phase and enhances lithium-ion mobility. The interconnected lithium pathways within the cubic lattice enable fast ion transport while maintaining structural robustness under electrochemical cycling. This makes LLZTO particularly attractive for solid-state electrochemistry and next-generation energy storage research.
