    摘要： A method for manufacturing a secondary battery includes manufacturing an electrode assembly having a stacked structure in which a negative electrode, an individual layer of a separator, a positive electrode, and an individual layer of the separator are repeated by alternately inserting the positive electrode and the negative electrode between the adjacent individual layers of the separator. Fold lines are formed on the separator at a predetermined interval, and the separator is folded in a zigzag shape along a vertical direction by the fold lines to form the plurality of individual layers; inserting the electrode assembly into a pouch; and discharging a gas from the Each of the positive electrode and the negative electrode is manufactured in a square shape so that remaining three sides except for one side facing the fold lines are opened.

    摘要： A secondary battery and a module thereof is disclosed, which has an electrode assembly and a case into which the electrode assembly is inserted. The case has an inner side with a coating layer containing a gas absorbing material, which absorbs or desorbs internal gas depending on the temperature inside the case. The secondary battery may enhance safety, in terms of improving battery heat transfer and preventing fire, by not only absorbing internal gas at normal operating temperatures but also desorbing internal gas at high temperatures. This may allow the secondary battery to regulate the internal gas emission point based on an internal pressure critical point when the battery is exposed to an abnormally high temperature. In addition, the secondary battery inhibits deformation of the battery case and is highly effective in preventing degradation of the battery performance by regulating the pressure inside the battery case.
