Synthesis of Li1.3Al0.3Ti1.7(PO4)3 Solid Electrolyte from Oxalate Precursor
A new efficient method for the synthesis of solid electrolyte with high lithium-ion conductivity with NASICON structure of composition Li1.3Al0.3Ti1.7(PO4)3 (LATP) has been proposed. The advantage of the developed method is the use of liquid-phase precursor based on titanium oxalate complex. A single-phase well-crystallized LATP has found to form at 750°C. The total ionic conductivity value of LATP after sintering at 900°C measured by impedance spectroscopy has been found to be of 2.6 × 10–4 S/cm at ambient temperature, while activation energy of conductivity has been found to be of 0.28 eV. The proposed method of synthesis is promising for scale-up and mass production.
