Document Type and Number:
Japanese Patent JP6796417
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a laminate type storage element having a structure capable of surely providing a short circuit between electrode terminal plates, which is a thin type, in a low cost.SOLUTION: A laminate type storage element 1 in which a sheet electrode body 10 is sealed in an external casing 11 formed by laminate films (11a and 11b) formed in a flat-bag shaped, comprises: electrode terminal parts (25 and 35) connected to each of a positive electrode 20 and a negative electrode 30 and conducted from a predetermined edge side of the external casing body. The external casing body is melted in a peripheral edge region 12 periphery rounding the laminate films faced each other while aligning an outer form. Each laminate film is melted through tab films (14a and 14b) in a region along the predetermined edge side in the peripheral edge region in which an insulation resin layer is formed on front and back surfaces of a metal foil material, and a base material end surface 11c is exposed in a predetermined edge side 13. Each tub film is deviated to an outer direction of the external casing in the region of one part of the predetermined edge, and comprises a deformation part 14c formed in a form covering the front and back surfaces of base terminals (26 and 36) of an electrode terminal part.SELECTED DRAWING: Figure 7
