| Abstract: The lithium ion-conductive solid electrolyte in the oxide systems of Li2O-TiO2-SiO2-P2O5 and Li2O-TiO2-Al2O3-P2O5 was prepared by solid-state reaction. The electrolyte pellets by cold-pressing method is 13 mm in diameter, about 1 mm in thickness. Phase identification and surface morphology of the products were carried out by X-ray diffraction and scanning electron microscopy. Ionic conductivity of the pellets was investigated through AC impedance. The results show that adulterate other cations can improve the ionic conductivity of the solid electrolyte. The maximum ionic conductivity in the samples is 9.912 × 10-4 S·cm-1 in the Li2O-TiO2-SiO2-P2O5 system. |
