PROBLEM TO BE SOLVED: To provide a manufacturing method of a cross-linked polymer electrolyte wall that has no pin hole and has uniform thickness and excellent quality. SOLUTION: The cross-linked polymer solid electrolyte wall is manufactured as follows; firstly a laminate comprised of a layer structure of a resin composition (A) layer/a resin composition (B) layer/a resin composition (A) is formed by a joint extrusion process and then the resin composition (B) layer is applied a cross-linked treatment by an energy of either of heating, ultraviolet rays or electron beam, and the resin composition (A) layer is separated from the resin composition (B) layer, thereby forming the cross-linked polymer solid electrolyte wall. Resin composition (A): polyolefin group resin or polyester group resin. Resin composition (B): Resin composition composed of a polyether copolymer such as copolymer of poly (ethileneoxide/epichlorohydrin) within the range of polymerization ratio of 85/15 to 99/1 of ethylene oxide and epichlorohydrin and lithium ion group salt such as lithium imide salt as electrolyte, and cross-linking agent. |
