Enhancement of ionic conductivity by addition of LiAlO2 in Li6.6La3Zr1.6Sb0.4O12 for lithium ion battery
Abstract Li6.6La3Zr1.6Sb0.4O12 has been synthesized by solid state reaction and effect of addition of LiAlO2 on density, structure and ionic conductivity has been studied. XRD pattern is studied for phase confirmation. Density has been calculated and SEM analysis has been done for morphological studies and elemental distribution in the sample. Complex impedance analysis was used to measure ionic conductivity of all samples and transport number measurement has been carried. Highest conductivity of 3.16 × 10−4 Scm−1 at 25°C is observed for 1 wt% LiAlO2 added Li6.6La3Zr1.6Sb0.4O12 ceramic sintered at 1050 °C for 8 h.
