Electrochemical stability of Li6.5La3Zr2M0.5O12 (M = Nb or Ta) against metallic lithium

Electrochemical stability of Li6.5La3Zr2M0.5O12 (M = Nb or Ta) against metallic lithium

The electrochemical stability of Li6.5La3Zr1.5Nb0.5O12 (LLZNO) and Li6.5La3Zr1.5Ta0.5O12 (LLZTO) against metallic Li was studied using direct current (DC) and electrochemical impedance spectroscopy (EIS). Dense polycrystalline LLZNO (ρ=97 %) and LLZTO (ρ=92 %) were made using sol-gel synthesis and...
