    Abstract

    Lithium garnet oxides of the composition series Li 7-xLa 3Zr 2-xTa xO 12 (x 0-2) were synthesized by the solid state reaction and characterized by the powder X-ray diffraction and the impedance spectroscopy. Single cubic phases were obtained between x 0.2 and 2, while the end-member Li 7La 3Zr 2O 12 exhibited a tetragonal phase. The lattice parameters of the cubic series followed the Vegards law. The maximum bulk (9.6 10 -4 Scm) and total (6.9 10 -4 Scm) conductivities were achieved at x 0.3 and x 0.2, respectively at room temperature. Electrochemical tests with a hybrid solid|liquid electrolyte configuration were performed to evaluate the electrochemical performance of the solid electrolytes.
