PRECURSOR COMPOSITION FOR SOLID ELECTROLYTE, AND METHOD FOR MANUFACTURING SECONDARY CELL
To provide a precursor composition for a solid electrolyte, whereby high lithium ion conductivity can be realized even when the precursor composition is sintered at a temperature of 1000 DEG C or less. This precursor composition for a solid electrolyte is a garnet-type or garnet-like-type precursor composition for a solid electrolyte including Li, La, Ar, and M, wherein M is one or more elements from among Nb, Ta, and Sb, the Li:La:Zr:M composition ratio in the solid electrolyte is 7-x:3:2-x:x, where the expression 0 < x < 2.0 is satisfied, and peaks in X-ray diffraction intensity occur in the X-ray diffraction pattern thereof at diffraction angles 2[theta] of 28.4 DEG, 32.88 DEG, 47.2 DEG, 56.01 DEG, and 58.73 DEG.
本发明提供即使在1000℃以下的温度进行烧结也能够实现高锂离子传导率的固体电解质的前体组合物。本申请的固体电解质的前体组合物是包含Li、La、Zr以及M的石榴石型或类石榴石型的固体电解质的前体组合物，M是Nb、Ta、Sb中的一种以上的元素，固体电解质中的Li:La:Zr:M的组成比是7‑x:3:2‑x:x，满足0＜x＜2.0，在X射线衍射图谱中，衍射角2θ是28.4°、32.88°、47.2°、56.01°、58.73°时显示出X射线衍射强度的峰。
