✦ Synopsis

A Li,O-AI,O,-TiO,-PzO, glass was prepared and converted into glass-ceramics through heat-treatment at 700-1000°C for 12 h. X-ray analysis indicated that the resultant glass-ceramics were mainly composed of Li, + \Al,Ti> (PO,), phases. The lithium ion conductivity of the glass-ceramics increased with the growth of the Li, +.AI,Ti,..,(PO,), phase and a extremely high value, 1.3 X 10m7 S cm-', was obtained at room temperature. This value is as large as that of Li,N which is well known to exhibit the highest lithium ion conductivity for a solid electrolyte.
