電気化学デバイス
Document Type and Number:
Japanese Patent JP4021592
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To improve cycle life and storage stability at high temperatures, by interposing an adhesive layer between a metal and a resin, which is sealed to the jacket bag of a laminated film having a metal layer and a resin layer and is laminated directly by a lead-through terminal for the outside, and a polyolefin resin layer to coat the layer between the lead-through terminal of a sealing part and the jacket bag. SOLUTION: In this electrochemical device 1, an electrochemical element is sealed by first and second sealing parts which are thermally bonded to the jacket bag of a laminated film 30, having a metal layer and a thermally adhesive resin layer. Lead-through terminals 13, 14, running outside through the second sealing part of the electrochemical element, directly laminate an adhesive layer 41 between the metal and the resin. The read-through terminals 13, 14 causes interpose an intermediate layer 40 comprising a polyolefin resin layer 42 for coating the adhesive layer 41 to interpose between the metal and the resin between the lead-through terminal and the jacket bags. Thereby, the electrochemical device sealed is given sufficient adherence between the jacket bag and the lead-through terminal.
