Lithium ion conduction in LiTi2(PO4)3

Abstract Li + ion conduction was examined for a mixture of LiTi 2 (PO 4 ) 3 (LTP) and a glassy electrolyte, 0.01Li 3 PO 4 –0.63Li 2 S–0.36SiS 2 . The addition of LTP with 10 wt.% resulted in a significant decrease in activation energy for conduction and little influence on the Li + ion conductivity, although it reduced the conduction path in the glass. The 7 Li NMR spectra of LTP was quite similar to that of Li 1.3 Al 0.3 Ti 1.7 (PO 4 ) 3 (LATP) with a high conductivity of 10 −3 S cm −1 . These results suggest that Li + ion conduction in LTP is as high as that in the glassy electrolyte and LATP.
