description A battery cell includes: a housing having a prismatic shape with a venting side and a terminal side that is different from the venting side; an electrode assembly inside the housing; a terminal arranged on the terminal side; and a venting valve on the venting side. The venting valve is configured to switch between a closed state and an open state. The venting valve, when in the open state, forms a vent opening in the venting side of the housing, and the vent opening is at least 15% of the total area of the venting side.
