Title:
電気化学セル及び電気化学セルの製造方法
Document Type and Number:
Japanese Patent JP6558810
Kind Code:
B2
Abstract:
To provide an electrochemical cell which can easily prevent a resin melted in melting from contacting an electrode body, and has high reliability, and a method for manufacturing the electrochemical cell.SOLUTION: An electrochemical cell includes an electrode body 2, metal layers 21 and 41, a first sheet 10 and a second sheet 11 which are formed of a laminate material including resin layers 22, 23, 42 and 43 covering the metal layers 21 and 41, and an exterior body 3 sealing the electrode 2, where the exterior body 3 includes a storage part 58 storing the electrode body 2 with the first sheet 10 and the second sheet 11 and a polymerization part 59 which is formed by overlapping the first sheet 10 and the second sheet 11 and surrounds the periphery of the storage part 58, where the polymerization part 59 includes a weld part S1 in which inside resin layers 22 and 42 of the first sheet 10 and the second sheet are welded to each other and a non-weld part S2 that is alternately arranged with the weld part S1 and in which the inside resin layers 22 and 42 of the first sheet 10 and the second sheet 11 are not welded to each other.SELECTED DRAWING: Figure 4
