Lithium ion conductors based on LiTi2P3O12 compound

The experimental results of Li1 + xTi2 − xCrxP3O12 system are given and the main factors showing influence on the lithium ion conductivity are discussed from the comparison of the Li1 + xTi2 − xMxP3O12 systems, where M = In, Cr, Ga and 0.5 Mg. The polarizability of the substituting ions and the concentration of the transferable ion are emphasized.
