摘要：
The ion transport properties of perovskite-type compounds (Li0.25La0.25)(1-x)Ca0.5xTaO3, as lithium ionic conductors, are investigated (0 <= x <= 0.5). The compounds were synthesized by using a solid state reaction. X-ray diffraction (Li0.25La0.25)(1-x)Ca0.5xTaO3 indicates a structure that is transformed from cubic to tetragonal. The ion conductivity of lithium at room temperature decreases with an addition Ca2+ as a result of the decrease in lattice parameters resulting from the Ca2+ concentration.
