Title:
扁平型電気化学セル
Document Type and Number:
Japanese Patent JP5320717
Kind Code:
B2
Abstract:
To provide a flat type electrochemical cell for a lithium ion battery or the like in which the deterioration of an insulation property of a packing material caused by a thin thickness of a thermal adhesive resin layer at heat sealing can be prevented irrespective of a lamination composition of the packing material, and durability and safety are excellent while securing airtightness even if it is used for a long time.
In the flat type electrochemical cell 1 accommodating an airtight flat type electrochemical cell body 2 in a packing material 5, the packing material 5 is thermally adhered to a circumferential portion 5c of the packing material 5 with an insulating film 10 between.
