Synthesis and Transport Properties of Triple Molybdate Na<sub>1–<i>x</i></sub>Mg<sub>1–<i>x</i></sub>In<sub>1+<i>x</i></sub>(MoO<sub>4</sub>)<sub>3</sub> 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<sub>1-<i>x</i></sub>Mg<sub>1-<i>x</i></sub>In<sub>1+<i>x</i></sub>(MoO<sub>4</sub>)<sub>3</sub> (<i>x</i> = 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 <i>R</i><mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mover><mml:mi>3</mml:mi><mml:mo>¯</mml:mo></mml:mover></mml:math><i>c</i>, <i>Z</i> = 6). The results of impedance and <sup>23</sup>Na NMR spectroscopy, as well as BVSE and DFT calculations, revealed the occurrence of rather fast translational diffusion of sodium atoms with an activation energy, <i>E</i><sub>a</sub> ≈ 0.7 eV.
