| 英文摘要 | Li7La3Zr2O12 (LLZO) with garnet structure has been acknowledged as a promising solid electrolyte for the next generation Li-ion batteries owing to its high chemical stability against Li metal and relatively high Li-ion conductivity. In this work, Li7-3xFexLa3Zr2O12 ceramics were prepared by the Pechini method. The influence of Fe substitution on the structure and microstructure of LLZO powder and ceramic were investigated by X-ray diffraction (XRD), TG (DSC)-MS, Raman spectroscopy, scanning electron microscopy (SEM), and impedance spectroscopy. TG-MS and XRD results indicated that LLZO powder could be formed around 750 degrees C. SEM results showed that the introduction of Fe accelerated densification of LLZO ceramic. The relative density of the composition with x = 0.2 was approximately 95.6%. Its ionic conductivity and activation energy were 4.28 x 10(-4) S/cm and 0.27 eV at 30 degrees C, respectively. |
