Zusammenfassung:Disclosed is a cell pouch film and a method for preparing the same, secondary battery using the same, and a method for manufacturing the secondary battery, wherein the cell pouch film includes at least an outer layer, a barrier layer, and a sealant layer which is an inner layer, the outer layer comprises a PET film of 7 to 12 μm on an outer side and a nylon film of 20 to 30 μm in an inner side, the barrier layer has a thickness of 60 to 80 μm, and the inner layer has a thickness of 60 to 100 μm. The cell pouch film is excellent in insulation resistance properties while having high rigidity and high formability, and this is useful as a medium and large size, particularly next-generation cell pouch for electric vehicles.
