Consolidation of al and Ta-substituted Li<sub>7</sub>La<sub>3</sub>Zr<sub>2</sub>O<sub>12</sub> powders with lithium-ion conductivity by s

Monophase powders of cubic modification with nominal composition Li6.4Al0.2La3Zr2O12 (Al–LLZ) and Li6.52Al0.08La3Zr1.75Ta0.25O12 (Ta–LLZ) were synthesized. Dense (~97–98%) ceramic samples of solid electrolyte with increased stability in air were obtained from these powders by spark plasma sintering. High Li-ion conductivity (4–6×10–4 S/cm) corresponding to the world level have been achieved.

Abstract

Monophase powders of cubic modification with nominal composition Li6.4Al0.2La3Zr2O12 (Al–LLZ) and Li6.52Al0.08La3Zr1.75Ta0.25O12 (Ta–LLZ) were synthesized. Dense (~97–98%) ceramic samples of solid electrolyte with increased stability in air were obtained from these powders by spark plasma sintering. High Li-ion conductivity (4–6×10–4 S/cm) corresponding to the world level have been achieved.
