- •
Cubic Li7La3Zr2O12 electrolyte was synthesized by Chemical co-precipitation method.
- •
Tetragonal LLZO transformed into cubic LLZO when the temperature was above 1150 °C.
- •
The particle size of LLZO precursor powder was in the range of 0.5 ~ 1 μm.
- •
The total ionic conductivity of sample sintered at 1180 °C was 2.0 × 10− 4 S cm− 1 at 30 °C.
- •
The activation energy was 0.25 eV.
