Abstract

Monophasic powders of the cubic modification and the nominal composition Li_6.4Al_0.2La₃Zr₂O₁₂ (Al-LLZO) and Li_6.52Al_0.08La₃Zr_1.75Ta_0.25O₁₂ (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.

放电等离子烧结Al和ta取代Li7La3Zr2O12粉末的强化研究

合成了名义成分为Li6.4Al0.2La3Zr2O12 （Al-LLZO）和Li6.52Al0.08La3Zr1.75Ta0.25O12 （Ta-LLZO）的立方改性单相粉末。用火花等离子烧结的方法从这些粉末中获得致密（~ 97-98%）的固体电解质陶瓷样品，其在空气中的稳定性增强。锂离子电导率达到世界水平（4-6 × 10-4 S/cm）。
