Abstract

The dependence of lithium ion conductivity on barium loading was investigated for Li0.33BaxLa0.56-2/3xTiO 3 (LBLT, 0 & x 0.1) ceramics. The highest bulk conductivity, σdc, of 1.24 × 10- 3 S cm- 1 obtained for 0.25 mol.% Ba loading was slightly improved compared to that of non-doped Li0.33La0.56TiO3 (1.18 × 10- 3 S cm- 1). The intensities of the XRD patterns in the independent cubic and tetragonal reflections, i.e., Ic(100) and It(101), were analyzed; a larger Ic(100)/I t(101) ratio corresponded to a larger σdc. A possible reason for the only slight enhancement of the σdc by a small loading of Ba is an increased volume fraction of the more highly conductive LBLT cubic phase.
