Fast Li-ion conducting glass-ceramics were obtained by heat-treating glasses in this system. The glass-ceramics were composed mainly of LiTi2(PO4)3, in which the Ti4+ ions were partially replaced by Al3+ or Ga3+ ions. Such substitution led to a considerable enhancement of the conductivity. The maximum room temperature conductivity which was obtained was 0.0013S/cm in the Al system and 0.0009S/cm in the Ga system.
