Lithium ionic conductivity of Li7-3xFexLa3Zr2O12 ceramics by the Pechini method

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...
