Preparation and evaluation of high lithium ion conductivity Li1.3Al0.3Ti1.7(PO4)3 solid electrolyte obtained using a new solution method
چکیده انگلیسی


• NASICON-type LATP powders were synthesized by a simple solution method.
• The dense LATP electrolyte was obtained at a low sintering temperature.
• The highest total conductivity at 25 °C is 1.21 × 10− 3 S cm− 1.

A NASICON-type (Na ion super conductor) structured Li1.3Al0.3Ti1.7(PO4)3 (LATP) solid electrolyte with high lithium ion conductivity was synthesized using a simple solution method with 85% H3PO4 solution. In comparison with conventional solid-state reaction and sol-gel method, the pure LATP powders and dense LATP pellets were obtained at a relatively lower temperature. The LATP powders and the resultant pellets were characterized by X-ray diffraction, scanning electron microscopy (SEM) and AC impedance spectroscopy. The LATP pellet obtained at 800 °C for 12 h shows the highest total conductivity of 1.21 × 10− 3 S cm− 1 at room temperature and the lowest activation energy of 0.26 eV. These results imply that the LATP electrolytes obtained using this method can be considered as candidates for solid state electrolytes.
