Abstract
A lithium-lanthanum-titanium oxide sintered material has a lithium ion conductivity 3.0×10Scmor more at a measuring temperature of 27° C., the material is described by one of general formulas (1-a)LaLiTiO-aSrTiO, (1-a)LaLiTiO-aLaKTiO, LaLiTiMO, and SrLaLiTiTaO(0.55≦x≦0.59, 0≦a≦0.2, M=at least one of Al, Fe and Ga), and concentration of S is 1500 ppm or less. The material is obtained by sintering raw material powder mixture having S content amount of 2000 ppm or less in the entirety of raw material powders for mixture, that is, titanium raw material, lithium raw material, and lanthanum raw material.
