Pouch-Shaped Battery Cell Manufacturing Method Including Secondary Sealing and Pouch-Shaped Battery Cell Manufactured Thereby

The prevent invention relates to a pouch-shaped battery cell manufacturing method including receiving an electrode assembly in a battery case made of a laminate sheet, primarily sealing an outer edge of the battery case, and secondarily sealing at least a part of the primarily sealed outer edge, wherein sealing force of a sealed portion formed after both the primary sealing and the secondary sealing are performed is low, whereby it is possible to induce the venting position and venting time of a pouch-shaped battery cell.
