Pouch Type Secondary Battery And Method For Manufacturing The Same

A method for manufacturing a pouch type secondary battery, the method comprising:

• preparing a pouch type exterior comprising a first area and a second area;
• pressing a portion of the first area to form a recess part in the first area;
• accommodating an electrode assembly having a first width in the recess part;
• rotating the second area about a folding area to fold the second area with respect to the first area such that the first area and the second area face each other;
• pulling the second area toward an end opposite to the folding area;
• and
• bonding at least a portion of a circumferential area of the first area to at least a portion of a circumferential area of the second area to form a sealing part,
• wherein the recess part includes a main recess part and a sub recess part,
• the main recess part including a space having a second width that is equal to or greater than a first width,
• the sub recess part being in communication with the main recess part and defining a space having a third width less than the first width.
