Title:
BATTERY CELL FOR ELECTRIC VEHICLE BATTERY PACK
Document Type and Number:
WIPO Patent Application WO/2020/048155
Kind Code:
A1
Abstract:
A battery cell of a battery pack to power an electric vehicle can include a housing to at least partially enclose an electrolyte material. 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. The scoring pattern can define a scored region on the vent plate. The battery cell can include a second polarity terminal including at least a portion of the vent plate. The battery cell can include an electrically conductive polymer tab to electrically connect the electrolyte material to the second polarity terminal. A first end of the polymer tab can be electrically coupled with the vent plate at an area within the scored region defined by the scoring pattern. A second end of the polymer tab can be electrically coupled with the electrolyte material. The polymer tab can melt in response to either a threshold temperature or a threshold current within the battery cell.
