LLZTO

A Garnet Solid-state Electrolyte Compatible with high voltage cathodes for high performance solid-state batteries Overview | Product Information | MSDS | Literature | Related Products | Technical Support LLZTO (CAS 1980850-22-3) is tantalum-doped lithium lanthanum zirconium oxide, used as a solid-state electrolyte. LLZTO exhibits high ionic conductivity of 10-4 – 10-3 S/cm at room temperature, making it one of the most promising candidates for solid-state batteries. LLZTO is compatible with high voltage cathodes (e.g. high-Ni NMC) and lithium metal, due to its wide electrochemical window. Incorporating LLZTO into a lithium iron phosphate (LFP) cathode significantly enhances the electrochemical performance. Galvanostatic charge-discharge and cyclic voltammetry profiles confirm reduced polarization and voltage hysteresis, consistent with improved ionic transport and lower interfacial resistance. The cathode composite maintains stable operation for over 200 cycles with 95% capacity retention and an average Coulombic efficiency of 99.6%.
