| Abstract: | The Al-substitution effect was studied in solid solutions La4/3-yLi3y□2/3-2yTi2O6 (LLTO). The ionic conductivity strongly depended on the Al concentration. The crystal structure, lattice parameters, ions occupation and bottleneck size were obtained by Rietveld analysis. Finally, the ionic conduction mechanism was discussed from the viewpoint of crystallographic factors. |
