Abstract: The present disclosure provides a pouch-type secondary battery, which comprises an electrode assembly, a packaging film. The packaging film comprises a first receiving portion, a second receiving portion, a third receiving portion. The third receiving portion is parallel to the first receiving portion, a portion of the electrode tab extends out of the third receiving portion. A joint location between the second receiving portion and the first receiving portion and a joint location between the second receiving portion and the third receiving portion each are formed with a bending angle, the bending angles are equal and each range from 130° to 160°. Because the bending angles in the range are relatively large, when the packaging film is tightly pressed, there is no need to apply a too large pressure on the second receiving portion and the third receiving portion, so the electrode tab is not easily damaged or even ruptured.
