LLZTO (Li7La3Zr2O12) is a lithium-ion conductive ceramic material that is widely used in the production of solid-state batteries. It has high lithium-ion conductivity and thermal stability, making it suitable for use as a solid electrolyte in all-solid-state batteries. LLZTO is also a common material used as a substrate in the production of thin-film solid-state batteries, due to its high resistance to thermal expansion and high electrical conductivity. This makes LLZTO a promising material for energy storage applications and in the development of new battery technologies.
