Abstract
(EN)
The present invention relates to a pouch-type battery cell, and a battery module and battery pack comprising same, the pouch-type battery cell comprising a battery case comprising a metal layer and a polymer resin layer, wherein the battery case has an electrode assembly accommodation part formed in at least one of an upper case and a lower case, and a venting member is positioned, as a portion adjacent to a sealing part of the battery case, on the outer side surface of the electrode assembly accommodation part. The venting member consists of a shape memory alloy which is deformed so as to pass through the battery case when the temperature of the battery cell is increased.
