PROBLEM TO BE SOLVED: To provide a cross-linked polymer solid electrolyte capable of maintaining or improving mechanical strength, and capable of imparting high ion conductivity, and to provide a method of manufacturing the cross-linked polymer solid electrolyte. SOLUTION: The cross-linked polymer solid electrolyte is obtained by cross-linking treatment of a polyalkylene oxide containing solid electrolyte salt and a co-crosslinking agent by irradiation of electron beams. The co-crosslinking agent is a polyalkylene glycol (meth)acrylate represented by the formula (1) in which the weight average molecular weight is smaller than that of the polyalkylene oxide. R<SP>1</SP>is a hydrogen atom or methyl group, R<SP>2</SP>is a 2-4C divalent hydrocarbon group, and (n) is an integer of 1 to 23. COPYRIGHT: (C)2010,JPO&INPIT |
