ALLZTO Tantalum and Aluminum added the Lithium Lanthanum Zirconium Oxide

Overview

ALLZTO (Aluminium and Tantalum co-doped Lithium Lanthanum Zirconium Oxide) is a garnet-structured solid electrolyte powder designed for advanced solid-state lithium battery research. This material exhibits a cubic garnet phase, which is widely recognised for its high lithium-ion conductivity, excellent electrochemical stability, and compatibility with metallic lithium anodes.

Material Chemistry and Working Principle

The chemical composition Li₆.₇₅La₃Zr₁.₇₅Ta₀.₂₅Al₀.₂O₁₂ incorporates Ta and Al dopants to stabilise the cubic garnet structure and enhance lithium-ion transport.

• Tantalum substitution increases lithium vacancy concentration, improving ionic conductivity.
• Aluminium doping assists phase stabilisation and grain boundary conductivity during sintering.

Lithium ions migrate through interconnected octahedral and tetrahedral sites within the garnet lattice, enabling fast ion transport while maintaining electronic insulation—an essential requirement for solid electrolytes.
