摘要

A NASICON-type solid electrolyte Li1.3Al0.3Ti1.7(PO4)3(LATP) ceramic was prepared using the sol–gel synthesis technique. To improve the ionic conductivity of LATP ceramic, Sb2O3 was added. The effect of Sb2O3 on the structural, microstructural, and ionic conductivity of the LATP ceramic was investigated. IR spectra were studied to determine the structural groups present in the ceramic samples. The highest bulk conductivity of 3.95 × 10–3 Scm−1 at room temperature, a relative density of 84.01%, and a low activation energy of 0.17 eV is obtained for the 1wt% Sb2O3 added LATP ceramic. The Sb2O3 added LATP ceramics can be a promising electrolyte material for solid-state lithium-ion battery applications.
