  • Bulk Ionic Conductivity: up to 4 ~ 10 x 10-4 S/cm (0.4 ~ 1.0 mS/cm) at room temperature
  • Product Form: Ceramic disk (ceramic membrane)
  • Package: each sintered LLZO ceramic membrane is packaged using a patent-pending method to prevent the product from exposure to air and moisture.

In order to measure the ionic conductivity of the LLZO sample, you may consider coating LLZO with silver as Li-ion blocking electrodes by magnetron sputtering. Some other researchers have tried to use silver paste.

Applications: Solid state electrolyte material for all solid state lithium ion batteries. Tantalum doped LLZO, with nominal composition Li6.4La3Zr1.4Ta0.6O12 (Ta-doped LLZO), is used as a solid electrolyte material for Li-based solid state 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.
