홈페이지논문 초록 (Abstract)
In this study, the intention is the determination of the optimum laminate conditions for the improvement of the chemical resistance of the aluminum-pouch films that are widely used as a packaging material for the secondary battery. Here, the properties including the initial adhesive strength and the electrolyte resistance between the metal-film layer with aluminum and the sealant layer with cast polyprophylene (CPP) film were investigated. Regarding the lamination condition, the lamination temperature, speed, and pressure conditions were changed. A roll-to-roll dry lamination-coating system was used in the surface-treatment agent coating, adhesive coating, and film lamination. For the lamination conditions of the aluminum and CPP films, the initial adhesive strength of the laminated-pouch film manufactured with a 110oC temperature and a 6.0 M/min line speed is 1200 gf/15 mm. The measured adhesive strength of the 85 oC electrolyte resistance after its immersion for 7 days is 600 gf/15 mm.
