An electrochemical cell is provided with an enhanced pressure relief vent formed in a closed end of the cell container that allows for effective venting of gas from the closed end of the container. The cell includes 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 electrode, and an aqueous alkaline electrolyte, all disposed in the container. The cell further includes a pressure relief vent mechanism having an offset C-shaped reduced thickness groove formed in the end wall of the container. A cover can be welded to the closed end wall of the container over the pressure relief vent mechanism. |
