  "textContent": "Disclosed are a secondary battery pouch film and a method for designing same, and a secondary battery using same and a method for manufacturing same, the secondary battery pouch film having at least an outer layer, a barrier layer, and a sealant layer sequentially laminated therein, wherein the weight per unit volume of the secondary battery film is greater than 1.45 mg/mmand less than 1.6 mg/mm. Accordingly, by adjusting the weight per unit volume of the secondary battery pouch film and the weight of a pouch additionally used during forming, it is possible to very easily ensure the reliability and safety of the secondary battery pouch film while maximizing weight reduction. The secondary battery pouch film is particularly useful in the pouch manufacturing process for medium- to large-sized secondary batteries, especially secondary batteries for electric vehicles, which require weight reduction, reliability, and safety.",
