Abstract
Li 7 La 3 Zr 2 O 12 (LLZO) with cubic garnet type structure is a promising solid electrolyte. In this work, Li 6.925-3x Al x La 3 Zr 1.925 Sb 0.075 O 12 (0 ≤ x ≤ 0.1) electrolytes were prepared by conventional solid-state reaction. The influence of Sb-Al cosubstitution on the structure, microstructure and conductivity of Li 7 La 3 Zr 2 O 12 were investigated by X-ray diffraction (XRD), Raman spectroscopy, scanning electron microscopy (SEM) and impedance spectroscopy. Single cubic phase has been achieved for Li 6.925-3x Al x La 3 Zr 1.925 Sb 0.075 O 12 (x = 0–0.075). Suitable amount of Al-Sb cosubstitution accelerates densification and improves the ionic conductivity. Li 6.775 Al 0.05 La 3 Zr 1.925 Sb 0.075 O 12 exhibits highest relative densities (96.7%) and total ionic conductivity (4.10 × 10 −4  S/cm at 30 °C).
