【 摘 要 】

Li5.76La3Zr1.59W0.35Y0.06Al0.2O12 (W, Y, Al-LLZO) solid electrolyte was prepared using the solid-state reaction method. Effects of calcining time (t) on the crystalline structure, morphology, relative density and shrinkage, the total ionic conductivity of the prepared W, Y, Al-LLZO solid electrolyte were studied, respectively. Controlling suitable calcining time can stabilize cubic phase W, Y, Al-LLZO at room temperature and improve the relative density and the ionic conductivity of the solid electrolyte samples. The relative density and the room temperature ionic conductivity of the W, Y, Al-LLZO solid electrolyte calcined at 900 C for 6 h are 90.78 % and 2.31 10-4 S⋅cm-1 respectively.
