Kind Code:

A1

Abstract:

Provided are a solid electrolyte membrane having good properties, and a method for producing same. A solid electrolyte membrane 40 is composed of a non-woven fabric UFN (ultrafine fiber non-woven fabric) and solid electrolyte particles 4AP contained in the non-woven fabric UFN. The non-woven fabric UFN has a fiber (ultrafine fiber UF) made of a polar-filler-containing resin. A method for producing the solid electrolyte membrane 40 comprises: a step for preparing a non-woven fabric UFN having a fiber made of a polar-filler-containing resin; a step for applying a slurry S, which contains solid electrolyte particles 4AP, onto the non-woven fabric UFN; and a step for heating the slurry S on the non-woven fabric UFN while applying pressure. The non-woven fabric UFN is formed by forming the polar-filler-containing resin in the form of fibers through a laser electrospinning process.
