The evolution of the Li-ion displacements in the 3D interstitial pathways of the cubic garnet-type Li(7)La(3)Zr(2)O(12), cubic Li(7)La(3)Zr(2)O(12), was investigated with high-temperature neutron diffraction (HTND) from RT to 600 °C; the maximum-entropy method (MEM) was applied to estimate the Li nuclear-density distribution. Temperature-driven Li displacements were observed; the displacements indicate that the conduction pathways in the garnet framework are restricted to diffusion through the tetrahedral sites of the interstitial space.
采用高温中子衍射（HTND）技术从室温到 600°C 研究了立方石榴石型 Li(7)La(3)Zr(2)O(12)、立方 Li(7)La(3)Zr(2)O(12)中锂离子在三维间隙通道中的迁移演变；应用最大熵法（MEM）来估算 Li 核密度分布。观察到温度驱动的 Li 位移；这些位移表明，石榴石骨架中的传导通道仅限于通过间隙空间的四面体位置进行扩散。
