【 摘 要 】

Li5.76La3Zr1.59W0.35Y0.06Al0.2O12 (W, Y, Al-LLZO) solid electrolyte was prepared using the solid-state reaction method. Effect of lithium salts (LiOH, LiNO3, Li2CO3, Li2C2O2) on the crystal structure, morphology, relative density and shrinkage, total ionic conductivity of the prepared solid electrolyte were studied, respectively. W, Y, Al-LLZO solid electrolytes of preparation with LiOH, LiNO3, Li2CO3 and Li2C2O2 respectively are cubic phases at room temperature. The high the total ionic conductivity of 2.56×10-4 S•cm-1 at 25 °C is achieved in W, Y, Al-LLZO solid electrolyte of preparation with Li2CO3.
