Abstract
A pouch-type battery cell includes a battery case including a metal layer and polymer resin layer, and an electrode assembly disposed within the battery case, the battery case further including an electrode assembly receiving part formed in at least one of an upper case and a lower case of the battery case, and a venting member disposed on an outer surface of the electrode assembly receiving part at a location adjacent to a sealing part of the battery case, wherein the venting member is made of a shape memory alloy that is deformed to penetrate the battery case when a temperature of the venting member increases to a value above a transition temperature of the shape memory alloy. A battery module including the pouch-type battery cell, and a battery pack are also provided.
