General description

Battery-grade Al-doped Lithium Lanthanum Zirconate Oxide (LLZO) powder is a high-purity, inorganic material that is specifically designed for use in advanced battery applications. It is a white, crystalline powder with an average particle size of 5-6 microns and is composed of lithium, lanthanum, zirconium, oxygen, and a small amount of aluminum dopant. This material is known for its high ionic conductivity, which falls within the range of 0.01-0.1 mS/cm, making it an ideal electrolyte material for use in solid-state lithium-ion batteries. Moreover, the high purity and narrow particle size distribution of this powder make it well-suited for use in the precise and reproducible manufacturing of battery components.

Application

The primary application of Al-doped LLZO powder is in all-solid-state and hybrid electrolytes for lithium-ion batteries. The unique combination of properties, including its high lithium-ion conductivity, robust chemical stability, and wide electrochemical stability window, make it a promising candidate for the next generation of solid-state batteries. This material has the potential to replace the conventional liquid electrolyte in lithium-ion batteries, offering higher energy density, improved safety, and longer lifespan.

Features and Benefits

Our LLZO powder provides high ionic conductivity and consistent particle size for reproducible results.
