A battery cell of a battery pack to power an electric vehicle can include a housing to at least partially enclose an electrode assembly is provided. The battery cell can include a vent plate coupled with the housing via a glass weld at a lateral end of the battery cell. The vent plate can include a scoring pattern to cause the vent plate to rupture in response to a threshold pressure. A first end of a polymer tab can be electrically coupled with the vent plate at an area within a scored region defined by the scoring pattern. A second end of the polymer tab can be electrically coupled with an electrode assembly. The polymer tab can melt in response to either a threshold temperature or a threshold current within the battery cell.
