Abstract

Garnet-type Li7 − 3xAlxLa3Zr2O12 (x = 0.2) made of different ratios of powders with mixed pre-treatment conditions is prepared by using a microwave oven. Cubic crystallographic structure is successfully achieved after sintered at 1150 °C for only 30 min, which is much lower than the conventional sintering. The conductivity of the samples, which peaked at 60% of powders treated at higher temperature, is comparable to the ones made at much higher temperature with longer dwelling time in literatures. The comparable conductivity was attributed to the denser microstructure and lower activation energy owing to the effect of powers with mixed pre-treatment conditions. The trend of the conductivity versus the ratio of powders with mixed pre-treatment conditions fit well with the percolation model of dispersed ionic conductors. Therefore, powders with mixed pre-treatment conditions could be used as precursors to prepare lithium ion conductors at lower temperatures with less dwelling time, which is beneficial to retaining lithium stoichiometry and any other problems associated with high-temperature procedure.
