AB  - NASICON materials of the general formula AMM’(SiO4)x(PO4)3-x (A = Li or Na, M and M’ = Al, Ti, Sc or Zr) are investigated because they are promising solid-state electrolytes for Li- or Na-ion batteries. A novel sol-gel method was developed to prepare Li1.5Al0.5Ti1.5(PO4)3 in kg-level and at low cost with high phase purity. The lithium conductivity of the samples reached 5 × 10-4 S/cm at room temperature. Na3.4Sc2(SiO4)0.4(PO4)2.6 powders were synthesized via solid state reaction and the sodium conductivity of the samples at room temperature was  8 × 10-4 S/cm. These values place our materials among the best NASICON conductive materials reported to date. The impact of water on the measured conductivities and activation energies was also investigated for different NASICON compositions, as well as the stability of these electrolytes against electrode materials.
