Abstract

With the promise of its high conductivity, the ceramic Li_1.3Al_0.3Ti_1.7(PO₄) ₃ (x = 0.85) of Li_{3 - 2x}(Al_{1 -x} Ti_x)₂(PO₄)₃ (x = 0.55 to 1.0), as a lithium fast ionic conductor, is produced by a conventional solid-state reaction and introduced into the poly(ethylene oxide) (PEO)-based composite polymer electrolyte films (CPE) to improve their ionic conductivity. The CPE films are prepared by a solution-cast technique and their characteristics are investigated by several experimental techniques including X-ray diffraction (XRD), infrared (IR) spectra, differential scanning calorimetry (DSC), and scanning electron microscopy (SEM). As measured by electrochemical impedance spectrum (EIS) measurement, the temperature-dependent ionic conductivity of PEO-Li_1.3Al_0.3Ti_1.7(PO₄) ₃ film with EO/Li = 16 is maximized at 2.631 × 10^-6 S cm^-1 at room temperature and at 1.185 × 10^-4 S cm^-1 at 343 K, while the ionic conductivity of the PEO-LiClO₄-Li_1.3Al_0.3Ti_1.7(P O₄)₃ film with EO/Li = 8 is maximized at 7.985 × 10^-6 S cm^-1 at room temperature and at 1.161 × 10^-3 S cm^-1 at 373 K when Li_1.3Al_0.3Ti_1.7(PO₄) ₃ content is 15 wt.%.
