Abstract

In this paper, we report the effect of Y-doping for Nb in the garnet-like Li ₅La ₃Nb ₂O ₁₂ on Li-ion conductivity. The phase formation, microstructure and electrical conductivity studies were done using powder X-ray diffraction (PXRD), scanning electron microscopy (SEM), ⁷Li nuclear magnetic resonance (Li-NMR) and AC impedance spectroscopy. The formation of cubic garnet-like structure was observed for x up to 0.25 and additional impurity peaks were observed above x = 0.25 in Li ₅La ₃Nb _2-xY _xO _12-δ. ⁷Li MAS NMR exhibits a single peak close to a chemical shift value of 0 ppm with respect to LiCl which could be due to the fast conduction of Li ions. Lithium ion conductivity of 1.34 × 10 ^-5 and 1.44 × 10 ^-5 Scm ^-1 was observed for x = 0.05 and 0.1 members, respectively at 23°C in air.
