Effect of sintering temperature on Li1.2Ti1.8Al0.2(PO4)3 solid electrolyte prepared via conventional techniques

Abstract

Li1.2Ti1.8Al0.2(PO4)3 (LATP) has been synthesized via conventional solid state techniques to study the influence of sintering temperature on lithium ion conductivity between 800 to 1000 °C. The optimum sintering parameter were identify through bulk density measurement. The size of the particles was characterized via particle size analyzer. The electrical property was measured by impedance spectroscopy. The highest ionic conductivity was observed for the samples sintered at 900 °C. The fabrication of Li1.2Ti1.8Al0.2(PO4)3 solid electrolyte is consider to be use as electrolyte materials in lithium ion rechargeable batteries.
