Synthesis and characterization on garnet-type structure Li7La3Ce2O12 and its electrical properties.

In this work, we report a garnet-type lithium-ion conductor with the chemical formula of Li₇La₃Ce₂O₁₂ that prepared by conventional solid-state synthesis route. A pure phase of cubic garnet-type Li₇La₃Ce₂O₁₂ was obtained at 900°C for 12 hours with intermittence grindings. Purity of the samples were confirmed by using X-ray diffraction (XRD) technique. The electrical properties of the samples wereanalyzed using Impedance Spectroscopy (IS) technique. Results show that the electrical conductivity in Li₇La₃Ce₂O₁₂ is dominated by bulk effects.
