MANUFACTURING METHOD OF JOINED BODY FOR POLYMER SECONDARY BATTERY, AND MANUFACTURING DEVICE FOR THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain a joined body for a polymer secondary battery having a joined surface without disjoined part caused by air bubbles. SOLUTION: A manufacturing device for a joined body for a polymer secondary battery forms a laminated body 19 interposing a polymer electrolyte layer 17 between a positive electrode activator layer 13 of a positive electrode sheet 11 having the positive electrode activator layer 13 on the surface of a positive electrode current collector 12, and a negative electrode activator layer 16 of a negative electrode sheet 14 having the negative electrode activator layer 16 on the surface of a negative electrode current collector 15, by holding the laminated body 19 between a first press 21 and a second press 26, and by applying hot press molding. The central part of a hot press molding surface of the first press 21 and/or the second press 26 are formed so as to swell out to form a convex-shaped curved surface. The laminated body 19 is formed by successively applying hot press molding from the central part toward one end part or both end parts of the laminated body 19 by pressing the central part of the first press 21 and the central part of the second press 26, on the central part of the positive electrode current collector 12 and/or the central part of the negative electrode current collector 15 of the laminated body 19.
