Preparation of High Lithium-Ion Conductive Ceramic


Article Preview

Lithium ionic conductive solid electrolyte discs based on NASICON-type Li1+xGaxTi2-x(PO4)3 (x = 0.1 - 0.9) were prepared by a wet-chemical route at 1173 - 1273K. Crystalline phase, density, and electrical conductivity of the sintered discs were systematically investigated. Single phase of LiTi2(PO4)3 systems were obtained at the calcination temperatures above 773K. Maximum conductivity 7.3 x 10-4 S/cm at 303K and activation energy of 0.30eV were obtained for the Li1.25Ga0.25Ti1.75(PO4)3 discs sintered at 1223K.
