Provided are a battery cell and a battery module including the same, and more particularly, the battery cell can secure safety thereof, by forming an exhaust part in a predetermined region of a sealing part to have a sealing member thicker than the other region of the sealing part so that the exhaust part has relatively weaker adhesive strength than the sealing part not containing the exhaust part, and thus, the adhesive state of the exhaust part is broken when high pressure occurs within the cell due to overheat conditions such as overcharging or inner short circuits to cause a case of the cell to swell, thereby discharging out the substances within a pouch type secondary cell. |
