Abstract

A solid electrolyte material includes: Li 2+y Ge 1−x M x O 3 . x satisfies an equation of 0≤x<0.5. y satisfies an equation of −0.5<y<0.5. M represents at least one element selected from Mg, Al, Ti, V, Cr, Mn, Fe, Co, Ni, Zn, Ga, Zr, Sn, Nb, Sb, Cu, Sc, Ta, and Hf. Ge has a six-coordinate structure, or the solid electrolyte material has a crystal structure attributed to monoclinic, C12/c1.
