Abstract
A solid electrolyte separator sheet for a solid-state lithium-ion battery is provided. The solid electrolyte separator sheet may comprise a membrane including solid electrolyte particles, an ion conducting polymer electrolyte binder, and a filament-type binder comprising chopped nanofibers. The ion conducting polymer electrolyte may include in situ formed, polyethylene-oxide-like polymer electrolyte.
