Abstracts

EN

The perovskite lithium lanthanum titanate shows high ionic conductivity at room temperature. Doping the lithium lanthanum titanate by niobium preserves the perovskite structure, which is synthesized by ceramic technology at high temperature (1300°C). The X-ray diffraction and scanning electron microscopy results show that the samples exhibit single phase. AC impedance measurements indicate total conductivity of about 8.93 × 10^{-4} S/cm for composition of x = 0.05 at room temperature. The Raman spectra and cyclic voltammetry results of the compound are also reported.
