Abstract
Two Li<sub>1+</sub><i><sub>x</sub></i>Al<i><sub>x</sub></i>Ge<i><sub>y</sub></i>Ti<sub>2</sub><sub>-</sub><i><sub>x</sub></i><sub>-</sub><i><sub>y</sub></i>(PO<sub>4</sub>)<sub>3</sub> (0.2 ≤ <i>x</i> ≤ 0.8; <i>y</i> = 0.8, 1.0) solid solutions have been prepared\nas polycrystalline powders. These compounds crystallize in the NASICON-type structure,\n<i>R</i>3̄<i>c</i> space group, and the crystal structures have been characterized by the Rietveld method\nwith laboratory X-ray powder diffraction data. The cell parameters evolution along the two\nseries agrees with the substitution of larger Ti<sup>4+</sup> by smaller Ge<sup>4+</sup> and Al<sup>3+</sup> cations. The\nelectrical properties have been characterized by an impedance study. Bulk conductivity values\nat room temperature are close to 10<sup>-3</sup> S·cm<sup>-1</sup> with low activation energies (≈0.35 eV). The\ntrajectories of the Li<sup>+</sup> cations have been simulated from the bond valence sum calculation.\nStructural keys, which justify the high ionic conductivity and the low activation energy, are\ndiscussed.
