    Abstract: Disclosed herein is a pouch-type secondary battery and a manufacturing method thereof including. The pouch-type secondary battery includes an electrode assembly; an electrode lead extending from an electrode tab of the electrode assembly; an upper pouch; and a lower pouch. The upper pouch and the lower pouch include a sealed area where the edges are sealed and an unsealed area. An average thickness of the sealed area of the upper pouch and an average thickness of the sealed area of the lower pouch are equal to each other, and the average thickness of the unsealed area of the upper pouch is smaller than the average thickness of the unsealed area of the lower pouch, so that even if the thickness of the lower pouch is reduced during the sealing process of heat-sealing, the sealed area of the upper and lower pouches are formed with little difference in thickness.

  • Publication number: 20150253073
    Abstract: Provided is a re-liquefying method for a stored liquid which has a simple structure or operation and excellent process efficiency. Since the method does not use separate refrigerant, the structure or operation in the re-liquefying method is significantly simplified. In addition, since a portion of a main stream is separated to form a cycle similar to a refrigerant cycle which cools the mainstream, the process efficiency of the re-liquefying method is significantly improved. The above Abstract is a more accurate literal translation of the abstract from the original priority application than the PCT abstract.
