General description

Tantalum-doped lithium lanthanum zirconium oxide (LLZTO) is a ceramic electrolyte material (lithium ion conductor) and a promising candidate to act as a solid electrolyte for lithium-ion batteries. We offer LLZTO with average particle size of 1-2 µm and high ionic conductivity (10-5 to 10-4 S/cm)
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency. Click here for more information.

Application

Solid electrolytes conduct lithium ions at room temperature and can potentially replace conventional organic liquid electrolytes, which are flammable and toxic. Tantalum-doping improves the electrochemical stability of lithium lanthanum zirconate (LLZO) by stabilizing the cubic phase at room temperature. We offer Ta-doped LLZTO with compositional uniformity, a small particle size (average D50 1-2 µm), and low aggregation to facilitate densification and ionic transport
