Method for Manufacturing Solid Polymer Electrolyte/Electrode Composites, Battery Produced Using the Method and Method for Producing the Same

A battery obtained by a method comprising the steps of:

• a) providing a composite of a solid polymer electrolyte film and a thin film-shaped porous electrode obtained by a method comprising the steps of:
• i) coating on an electrode surface of said thin film-shaped porous electrode with a polymerizable compound which is converted to said solid polymer electrolyte or a pre-solid polymer electrolyte upon polymerization;
• and
• ii) reducing pressure inside said porous electrode after superposing said electrode surface coated with said polymerization compound onto said solid polymer electrolyte film,
• b) impregnating said porous electrode in said composite under reduced pressure with an electrolytic solution.
