Single phase of Li3AlN2 was prepared from the mixture of Li3N/AlN = 1.2 to 1.5 in molar ratio at 700°C and at 900°C. It crystalizes in the cubic system derived from antifluorite-type structure having the lattice parameter a = 9.470 A ̊. It is a pure ionic conductor having conductivity of 5 × 10-8 ω-1 cm-1 at room temperature and an activation energy of 52 kJ/ mol. Its decomposition voltage was 0.85 V at 104°C. The TiS2/Li3AlN2/Li cell could be discharged at a constant current of 45 μA/cm2 at 104°C.
