Lithium ion conductive glass-ceramics and electric cells and gas sensors using the same

摘要

Lithium ion conductive glass-ceramics comprise in mol %:where M is an element or elements selected from the group consisting of In, Fe, Cr, Sc, Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Th, Dy, Ho, Er, Tm, Yb and Luand contain Li1+X(M, Al, Ga)X(Ge1-YTiY)2-X(PO4)3 (where 0<X<=0.8 and 0<=Y<=1.0) as a predominant crystal phase. A solid electrolyte, an electric cell and a gas sensor utilizing these glass-ceramics are also provided.
