SOLID ELECTROLYTE FILM FOR SULFIDE-BASED ALL-SOLID-STATE BATTERY BATTERIES

A solid electrolyte film for sulfide-based all-solid-state batteries, and more particularly a composition of a solid electrolyte, a binder, and a solvent used to manufacture a solid electrolyte film for sulfide-based all-solid-state batteries that is thin and has high ion conductivity. In particular, a solid electrolyte film composition for sulfide-based all-solid-state batteries including a solvent having a dielectric constant of x (1.5
