| titleOfInvention | Manufacturing method of pouch film for secondary battery of lithium ion |
| abstract | The present invention relates to a method for manufacturing a pouch film for a lithium ion secondary battery, and an object of the present invention is to simultaneously improve the moldability of the pouch film and the chemical resistance to an electrolyte solution. To this end, the present invention, (a) forming a first surface treatment layer 12 on one side of the barrier film 11 with a micro gravure coating device 140a (S10), (b) the Forming a second surface treatment layer 15 on the other side of the barrier film 11 with a micro gravure coating device 140a (S20), (c) direct to the first surface treatment layer 12 Forming the first adhesive layer 13 with a gravure (Direct Gravure) coating device 140b (S30), (d) laminating and aging the protective film 14 to the first adhesive layer 13 ( S40), (e) forming a second adhesive layer 16 on the second surface treatment layer 15 with a slot die coating device 140c (S50), (f) the second adhesive A step (S60) of laminating and aging a sealant film 17 on the layer 16, wherein the barrier film 11 is made of aluminum foil having a thickness of 0.03 to 0.05 mm, , The protective film 14 is made of a nylon film with a thickness of 0.02 to 0.03 mm, and the sealant film 17 is made of cast polypropylene with a thickness of 0.03 to 0.05 mm. |
