Abstract
A main object of the present invention is to provide a solid electrolyte material having excellent Li ion conductivity. To attain the object, the present invention provides a solid electrolyte material represented by a general formula: Lix(La1-aM1a)y(Ti1-bM2b)zOδ, characterized in that “x”, “y”, and “z” satisfy relations of x+y+z=1, 0.652≦x/(x+y+z)≦0.753, and 0.167≦y/(y+z)≦0.232; “a” is 0≦a≦1; “b” is 0≦b≦1; “δ” is 0.8≦δ≦1.2; “M1” is at least one selected from the group consisting of Sr, Na, Nd, Pr, Sm, Gd, Dy, Y, Eu, Tb, and Ba; and “M2” is at least one selected from the group consisting of Mg, W, Mn, Al, Ge, Ru, Nb, Ta, Co, Zr, Hf, Fe, Cr, and Ga.
