We present a novel strategy to synthesize pure cubic garnet Li7La3Zr2O12 solid electrolyte at a relatively low temperature (700 °C) by two steps. During the process of obtaining Li7La3Zr2O12, the 8a oxygen vacancy in pyrochlore of La2Zr2O7 was used to occupy the “Li1” 8a site which the information of tetragonal phase Li7La3Zr2O12 requires lithium occupation. The lithium ion conductivity of the obtained cubic garnet Li7La3Zr2O12 as high as 1.7 × 10–4 S cm−1 at room temperature is consistent with the order of record conductivity in the literatures.
