ラミネート型蓄電素子およびラミネート型蓄電素子の実装方法

Japanese Patent JP6986347

B2

PROBLEM TO BE SOLVED: To provide a laminate-type power storage element in which an electrode body is prevented from being damaged due to a thermocompression bonding process and a short-circuit between electrode terminals can be reliably prevented.SOLUTION: In a laminate-type power storage element 1a, an electrode body 10 including sheet-like positive and negative electrodes 20 and 30 is sealed inside an exterior body 11 formed in a flat bag shape, and electrode terminal plates (23, 33) of the respective positive and negative electrodes are guided to an outside of the exterior body. Each of the electrode terminal plates is guided from a predetermined margin 13 of the exterior body in the same direction, and a film member 16 covering the electrode terminal plate along the predetermined margin is attached on one principal surface 51 side of the electrode terminal plate. The film member is formed by layering an adhesive 16b on a surface of an insulating heat-resistant film 16a, the adhesive being melted by thermocompression bonding. The adhesive of the film member is bonded to the one principal surface 51 of the electrode terminal plate and a region that does not face the one principal surface of the electrode terminal plate is in a meltable state during thermocompression bonding.SELECTED DRAWING: Figure 5
