Abstract
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<x<3.0). The thickness of a solid electrolyte film for sulfide-based all-solid-state batteries manufactured using the solid electrolyte film composition is 60 μm or less, and the solid electrolyte film is capable of being stably used for at least 1000 hours or more, and up to 2000 hours, based on the evaluation of Li plating and stripping.
