Abstract

For 7Li-enriched La2/3-x7Li 3xTiO3 samples quenched into liquid nitrogen and cooled in the furnace, impedance measurements and time-of-flight neutron powder diffraction (TOF-NPD) experiments were carried out in order to study the effect of the quenched-into-liquid-nitrogen treatment for the ionic conduction and the structural properties. It was found that the quenched-into-liquid-nitrogen treatment enhances the lithium ionic conductivity in the 7Li-content range between 3x ∼ 0.25 and 0.45. Furthermore, the local structure within 6 Å did not change, according to the atomic pair density function (PDF) analysis.
