NASICON-type conductors based on LiGe 2 (PO 4 ) 3 are very promising lithium-conducting electrolytes for all-solid-state lithium-ion and lithium batteries. Al-doped LiGe 2 (PO 4 ) 3 solid electrolytes possessed higher conductivity (∼10 -4 S/cm at room temperature) and stability versus metallic Li. In this paper, we present the structure study of Li 1.5 Al 0.5 Ge 1.5 (PO 4 ) 3 compound. Fast lithium-ion conductor Li 1.5 Al 0.5 Ge 1.5 (PO 4 ) 3 solid electrolyte have been obtained through glass crystallization at 820 °C during 8 h. Structural positions occupied by atoms have been examined by solid state nuclear magnetic resonance experiments. 6 Li, 7 Li, 27 Al и 31 P NMR measurements have been performed at room temperature.
