Product Details
Niobium-containing LLZTO Tantalum-niobium Co-doped Lithium
Lanthanum Zirconium Oxygen Solid Electrolyte (300nm) Battery
Material
Product Overview
Xwell's niobium-tantalum co-doped LLZTO (300nm particle size) is a
high-performance cubic garnet electrolyte for solid-state lithium
batteries. This white powder material delivers 0.8-3 mS/cm ionic
conductivity at room temperature while maintaining exceptional
stability with both cathode and anode materials.
