Lithium lanthanum zirconium oxide (LLZO, Li₇La₃Zr₂O₁₂) is a lithium-stuffed garnet material that is under investigation for its use in solid-state electrolytes.[1][2] LLZO has a high ionic conductivity, giving it an advantage for use as an electrolyte.[3]

Press reports have stated that LLZO is believed to be the electrolyte used by QuantumScape for their solid-state lithium metal battery.[4]
