Consolidation of Al and Ta-Substituted Li7La3Zr2O12 Powders with Lithium-Ionic Conduction by Spark Plasma Sintering
Monophasic powders of the cubic modification and the nominal composition Li6.4Al0.2La3Zr2O12 (Al-LLZO) and Li6.52Al0.08La3Zr1.75Ta0.25O12 (Ta-LLZO) are synthesized. Dense (~97–98%) solid-electrolyte ceramic samples with enhanced stability in air are obtained from these powders using the method of spark plasma sintering. The high Li-ionic conductivity (4–6 × 10–4 S/cm) corresponding to the world level is achieved.
