冷等静压法制备Li7La3Zr2O12固体电解质
Preparing Li7La3Zr2O12 solid electrolyte by cold isostatic pressing method
摘要
Abstract
Cold isostatic pressing method was employed to prepare Li7La3Zr2O12 (LLZO) solid state electrolyte.The crystalline structure,morphology,and electrochemical performance were characterized by XRD,SEM,AC impedance spectrum,Hebb-Wagner and cyclic voltammetry measurements.When the sintering temperature reached up to 1 150 ℃,a dense and pure cubic structure LLZO pellet was gained,with a total ionic conductivity of 1.07 × 10-4 S/cm and an electronic conductivity of 2.39 × 10-8 S/cm at room temperature.This sample was determined to be a nice ion conductor and electron insulator.In a wide electrochemical stable widow of 0-7 V(vs.Li +/Li),no distinct redox reaction was detected.关键词
