Lithium ion conduction in LiTi2(PO4)(3)

Li+ ion conduction was examined for a mixture of LiTi2(PO4)(3) (LTP) and a glassy electrolyte. 0.01Li(3)PO(4)-0.63Li(2)S-0.36SiS(2). The addition of L TP with 10 wt.% resulted in a significant decrease in activation energy for conduction and little influence on the Lif ion conductivity, although it r educed the conduction path in the glass. The Li-7 NMR spectra of LTP was qu ite similar to that of Li1.3Al0.3Ti1.7(PO4)(3) (LATP) with a high conductiv ity of 10(-3) S cm(-1). These results suggest that Li+ ion conduction in LT P is as high as that in the glassy electrolyte and LATP. (C) 2001 Elsevier Science B.V. All rights reserved.
