Description

LLZTO Tantalum-doped Lithium Lanthanum Zirconium Oxygen Solid Electrolyte Sheet Li6.5La3Zr1.5Ta0.5O12 Battery Material

Material Overview​​

LLZTO (Li₆.₅La₃Zr₁.₅Ta₀.₅O₁₂) is a cubic-phase garnet-type oxide solid electrolyte with superior ionic conductivity ( S/cm at 25°C) and exceptional electrochemical stability (0–5 V vs. Li⁺/Li). Its Ta doping stabilizes the cubic structure while suppressing lithium dendrite growth, making it ideal for lithium-metal batteries.

​​Key Properties​​

​​Parameter​​ ​​Specification​​
​​Crystal Structure​​ Cubic garnet (Ia-3d)
​​Density​​ >95% theoretical (5.1 g/cm³)
​​Thickness Options​​ 50–300 μm (customizable)
​​Ionic Conductivity​​ S/cm (25°C)
​​Activation Energy​​ 0.25–0.30 eV
​​Thermal Stability​​ Up to 1000°C (melting point)

​​Performance Highlights​​

  1. ​​Interface Engineering​​

    • Forms stable SEI with Li metal (critical current density: 4.2 mA/cm²)
    • Low interfacial resistance (<10 Ω·cm² with Sn:SnF₂ coating)

  2. ​​Mechanical Robustness​​

    • Vickers hardness: 8–10 GPa
    • Withstands >300 MPa assembly pressure

  3. ​​Battery Integration​​

    • Compatible with NMC811 cathodes (181 mAh/g initial capacity)
    • Stable cycling >3000 cycles (0.1C rate)

​​Applications​​

  • ​​All-Solid-State Lithium Batteries​​ (ASSLBs)
  • ​​Lithium-Sulfur/Lithium-Air Batteries​​
  • ​​Hybrid Solid-Liquid Electrolyte Systems​​

​​Handling Notes​​

  • ​​Storage​​: Argon glovebox (O₂/H₂O <0.1 ppm) to prevent Li₂CO₃ formation
  • ​​Processing​​: Cold-press at 300–500 MPa for pellet formation

Note: Custom formulations (e.g., Ga-doped LLZTO) and thicknesses available for research-scale orders.
