Synthesis of Li_6.25 Ga_0.25 La₃ Zr₂ O₁₂ (LLZO-Ga) solid electrolyte powder granule for all solid-state battery was investigated by applying mechanical processing of the raw powder materials adding LiF-BaF₂ as a flux. The LLZO-Ga of highly crystalline was synthesized by the mechanical method using an attrition-type mill without any extra-heat assistance. When 10 mass% of LiF-BaF₂ was added to the raw powder materials and 28 min processed, LLZO-Ga powder was favorably synthesized and granulated at the chamber temperature of 284 °C. The ionic conductivity of the sintered body of the LLZO-Ga granules was evaluated by impedance measurement. It revealed the high ionic conductivity of σ_total 1.0 × 10⁻³ S/cm. It suggests that the formation of LLZO-Ga/BaZrO₃ grain boundary contributes to higher ionic conductivity adding to the high crystalline phase of LLZO-Ga.

以LiF-BaF ₂作为助熔剂，对粉体原料进行机械加工，研究了全固态电池Li _6.25 Ga _0.25 La ₃ Zr ₂ O ₁₂ (LLZO-Ga)固体电解质粉末颗粒的合成。高度结晶的 LLZO-Ga 是通过机械方法合成的，使用磨损型磨机，没有任何额外的热辅助。当 LiF-BaF ₂为 10 质量％时向原料粉末材料中加入 28 分钟，LLZO-Ga 粉末在 284°C 的腔室温度下顺利合成和造粒。LLZO-Ga颗粒的烧结体的离子电导率通过阻抗测量来评估。它揭示了σ _total 1.0 × 10 ^-3 S/cm的高离子电导率。这表明LLZO-Ga/BaZrO ₃晶界的形成有助于提高LLZO-Ga 的高结晶相的离子电导率。
