摘要

寻找具有高离子电导率的含钠材料对钠离子电池技术的发展至关重要。本文介绍了固态合成新型三钼酸盐Na1-xMg1-xIn1 +x(MoO4)3 （x = 0.1-0.5）的综合实验和理论研究结果。通过x射线衍射检查晶体结构，确定其为NASICON型（空间群R3¯c， Z = 6）。阻抗和23Na核磁共振谱以及BVSE和DFT计算结果表明，钠原子发生了相当快的平移扩散，活化能Ea≈0.7 eV。

Synthesis and Transport Properties of Triple Molybdate Na1–xMg1–xIn1+x(MoO4)3 with the NASICON-Type Structure

The search for sodium-containing materials with high ionic conductivity is crucial for the development of sodium-ion battery technologies. This article presents the results of comprehensive experimental and theoretical studies of the novel triple molybdate Na_1–xMg_1–xIn_1+x(MoO₄)₃ (x = 0.1–0.5) obtained by solid-state synthesis. The crystal structure was examined by X-ray diffraction and assigned to the NASICON type (space group R

c, Z = 6). The results of impedance and ²³Na NMR spectroscopy, as well as BVSE and DFT calculations, revealed the occurrence of rather fast translational diffusion of sodium atoms with an activation energy, E_a ≈ 0.7 eV.
