POUCH TYPE SECONDARY BATTERY

摘要

PURPOSE: A pouch type secondary battery is provided to emit internal material of a pouch type secondary battery by releasing sealing of an exhaust part with a relatively lower adhesion than a sealing part, thereby obtaining safety. CONSTITUTION: A pouch type secondary battery(1000) comprises an electrode assembly(100) which comprises first and second electrodes and first and second electrode tabs(110,120) extended from the first and second electrodes; a pouch type battery case(200) which accommodates the electrode assembly and is sealed to expose the first and second electrode tabs outwards; a sealing part which is sealed by spreading sealing member to the adhesive side, to seal the pouch type battery case; and an exhaust part which has an exhaust member(410) inserted into the adhesive side of the sealing part and has a weaker adhesion than the adhesion of the sealing part.
