Preparation of High Lithium-Ion Conductive Ceramic

摘要

Lithium ionic conductive solid electrolyte discs based on NASICON-type LiB1+xBGaBxBTiB2-xB(POB4B)B3B (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 LiTiB2B(POB4B)B3B systems were obtained at the calcination temperatures above 773K. Maximum conductivity 7.3 x 10P-4P S/cm at 303K and activation energy of 0.30eV were obtained for the LiB1.25BGaB0.25BTiB1.75B(POB4B)B3B discs sintered at 1223K.
