Abstract
A production method for a halide solid electrolyte of the present disclosure includes: (A) converting a first composition containing Li, Ti, and O into a first halide containing Li, Ti, and X1; and (B) synthesizing a halide solid electrolyte containing Li, Ti, M, X1, and X2 using the first halide obtained in the (A) and a second halide containing Li, M, and X2. The M is at least one element selected from the group consisting of metal elements (excluding Li) and metalloid elements, the X1 is at least one selected from the group consisting of F, Cl, Br, and I, and the X2 is at least one selected from the group consisting of F, Cl, Br, and I.
