A modified sol-gel process was studied as applied to synthesize a lithium-conducting solid electrolyte of composition LiAlTi(PO) (LATP) using water-soluble salts Al(NO) · 9HO, LiNO · 3HO, and (NH)HPO and a titanium(IV) citrate complex. As-synthesized samples were characterized using X-ray powder diffraction, DSC/TG, SEM, and impedance spectroscopy. Sintering of as-synthesized amorphous powders at 700°C was found to yield LATP with crystallite sizes of 42-48 nm. Ionic conductivity of the electrolyte measured in the frequency range 25-10 Hz in disks having 86-90% density that were sintered at 1000°C was (3-4) × 10 S/cm. Temperature-dependent ionic conductivity was studied in the range 25-200°C. The activation energy of conduction was determined for LATP. [ABSTRACT FROM AUTHOR] |
