The Li+ ion conductivity was examined for a mixture of Ti2Li(PO4)3 with a glassy electrolyte (Li2S-0.36SiS2-0.01Li3PO4). The addition of Ti2Li(PO4)3 resulted in a marked decrease in the activation energy for conduction, but had little effect upon the Li+ ion conductivity (although it reduced the conduction path in the glass). The 7Li nuclear magnetic resonance spectrum of Ti2Li(PO4)3 was quite similar to that of Li1.3Al0.3Ti1.7(PO4)3, with a high conductivity (0.001S/cm). The results suggested that Li-ion conduction in Ti2Li(PO4)3 was as high as that in the glassy electrolyte or Li1.3Al0.3Ti1.7(PO4)3.
