摘要： Disclosed herein is a pouch-shaped secondary battery including a micro-perforated electrode lead having adhesive properties that is capable of enabling a short circuit to occur in the pouch-shaped secondary battery using the adhesive properties of the micro-perforated electrode lead with respect to a pouch-shaped battery case in order to secure the safety of the pouch-shaped secondary battery when the pouch-shaped secondary battery swells due to gas generated in the pouch-shaped secondary battery while the pouch-shaped secondary battery is in an abnormal state or when the pouch-shaped secondary battery is overcharged. Current is prevented from flowing in the pouch-shaped secondary battery when the pouch-shaped secondary battery is overcharged or when the pouch-shaped secondary battery is in an abnormal state.

摘要： A cylindrical battery cell is provided. The cylindrical battery cell configured to have a structure in which a wound type electrode assembly having a positive electrode/separator/negative electrode structure is mounted in a cylindrical can. The cylindrical battery cell includes an inorganic coating portion for accelerating dissipation of heat from the cylindrical can, the inorganic coating portion being provided on at least a part of the outer surface of the cylindrical can.
