Abstract

A solid electrolyte material of the present disclosure includes: Li; M; O; X; and A. The M is at least one selected from the group consisting of Ti, Zr, and Hf. The X is at least one selected from the group consisting of F, Cl, Br, and I. The A is at least one selected from the group consisting of P and B. A molar ratio of the Li to the M is 1.0 or more and 3.0 or less. A molar ratio of the O to the X is 0.2 or more and 0.7 or less. A molar ratio of the A to the M is 0.02 or more and 0.80 or less.
