Product Description
LLZTO Solid Electrolyte Material Overview
LLZTO (Li₆.₅La₃Zr₁.₅Ta₀.₅O₁₂) is a cubic-phase garnet-type oxide solid electrolyte featuring superior ionic conductivity of 1.68×10⁻³ S/cm at 25°C and exceptional electrochemical stability (0-5 V vs. Li⁺/Li). The tantalum doping stabilizes the cubic structure while effectively suppressing lithium dendrite growth, making it ideal for advanced lithium-metal battery applications.
