| description | An electrochemical cell is provided with an enhanced pressure relief vent formed in a closed end of the cell container that achieves effective venting of gas from the closed end of the container. The electrochemical cell including a container having a first end, a second end, a side wall extending between the first and second ends, and an end wall extending across the first end. The cell has a positive electrode, a negative, and an aqueous alkaline electrolyte, all disposed in the container. The cell further includes a pressure relief vent having a reduced thickness groove formed in the end wall of the container. The reduced thickness groove is formed having eight segments extending radially from a central location. A cover is welded on the end wall of the container via at least three welds, wherein the angular spacing between two adjacent welds is greater than 120°. |
