Abstract
The synthesis of lithium conducting solid electrolyte Li1.5Al0.5Ge1.5(PO4)3 (LAGP) by liquid-phase method from oxalate and citrate precursors is investigated. The samples were characterized by XRD, DSC / TG, IR, impedance spectroscopy and potentiostatic chronoamperometry. It was found that the formation of a single - phase LAGP from an oxalate precursor occurs at a lower temperature (600–650 °C) and is preferable compared to the synthesis of LAGP from a citrate precursor. The ionic conductivity of the electrolyte was 4,2 · 10-4 S / cm, the electronic conductivity did not exceed 2 · 10-10 S / cm, the decomposition potential was 3.8 V.
