Al-doped llzo
WebInorganic oxide-based solid electrolytes are among the most sought-after candidates for an all-solid-state battery. NEI supplies the following oxide-based electrolytes: “Fine LLTO” – Lithium Lanthanum Titanate (Li0.34La0.56TiO3), 1-2 µm “Fine LLZO” – Al-doped Lithium Lanthanum Zirconium Oxide (Li6.24La3Zr2Al0.24O11.98), 1-2 µm WebHerein, this effect is leveraged for preparation of Ta-doped LLZO (LLZTO, nominal composition Li 6.4 La 3 Zr 1.4 Ta 0.6 O 12), which is known to possess exceptionally high conductivity among Li garnets.41 Doping of LLZO with Ta is advantageous as Ta resides on the Zr sites in the garnet structure and therefore does not disrupt or impede Li ...
