520 _ _ |a Na+ Super-Ionic CONductors (NaSICON) consist of a 3D framework of corner-shared ZrO6 octahedra and (Si,P)O4 tetrahedra, joined by inter¬connected channels providing a Na+ conduction pathway between Na(1) and Na(2) positions. The original composition Na3Zr2Si2PO12 can be modified according to the generalized formula as Na1+2w+x-y+z M2+w M3+x M5+y Zr2-w-x-y (SiO4)z (PO4)3-z. To anticipate a fast conducting NaSICON material, the composition should follow specific design parameters:1. The size of transition metal cations (reff = 0.72 Å)2. The Na content (3 – 3.5 moles Na/formula unit)3. The crystal structure (monoclinic distortion affecting the structural bottleneck)So far three series of NaSICON materials were designed to verify the proposed design parameters: Na3+xScxZr2-xSi2PO12, Na3+xSc2SixP3-xO12 and Na1+2xAlxYxZr2-2xSiyP3-yO12. For the first two series the maximum conductivity was indeed obtained for x = 0.4, with the highest Na+ ion conductivity in polycrystalline NaSICON materials ever reported for Na3.4Sc0.4Zr1.6Si2PO12 (4 mS cm-1).
