Abstract
A solid electrolyte membrane having favorable characteristics and a method of forming the same are provided. A solid electrolyte membraneis composed of a non-woven fabric (ultrafine fiber non-woven fabric) UFN and solid electrolyte particlesAP incorporated therein. Also, the non-woven fabric UFN includes a fiber (ultrafine fiber UF) made of a resin containing a polar filler. A method of manufacturing the solid electrolyte membraneincludes a step of preparing the non-woven fabric UFN including a fiber made of a resin containing a polar filler, a step of applying a slurry S containing the solid electrolyte particlesAP onto the non-woven fabric UFN, and a step of heating while pressurizing the slurry S on the non-woven fabric UFN. Further, the non-woven fabric UFN is formed by making the resin containing the polar filler be a fibrous form by a laser electrospinning method.
