Fast lithium ion conducting glass-ceramics have been successfully prepared from the pseudobinary system 2[Li{sub 1+x}Ti{sub 2}Si{sub x}P{sub 3{minus}x}O{sub 12}]-AlPO{sub 4}. The major phase present in the glass-ceramics was LiTi{sub 2}P{sub 3}O{sub 12} in which Ti{sup 4+} ions and P{sup 5+} ions were partially replaced by Al{sup 3+} ions and Si{sup 4+} ions, respectively. Increasing x resulted in a considerable enhancement in conductivity, and in a wide composition range extremely high conductivity over 10{sup {minus}3} S/cm was obtained at room temperature.
