Abstract
A solid electrolyte composition includes a solvent and a solid electrolyte dispersed in the solvent. The solid electrolyte includes a halide solid electrolyte. The solvent has a polar component δp of Hansen solubility parameters that is greater than 0 and less than 5.9. The halide solid electrolyte contains Li, M1, and X1. M1 is at least one selected from the group consisting of metalloid elements and metal elements other than Li. X1 is at least one selected from the group consisting of F, Cl, Br, and I.
