摘要： Disclosed are a cell pouch film having improved formability, a method for preparing the same, and a secondary battery using the same. The cell pouch film can suppress the occurrence of cracks in edge portion generated during deep molding, allowing the edge portion to be formed thickly, thereby exhibiting excellent deep molding properties. Since such a cell pouch film can improve the energy density of a secondary battery, it is particularly useful as a medium to large-sized cell pouch for electric vehicles, energy storage devices, and the like.
