Abstract
An electrochemical cell is provided having a non-cylindrical container including one or more side walls each having a curved surface that curves radially inward. The electrochemical cell further includes first and second electrodes and a separator disposed therebetween. A cover and seal assembly is assembled to the top open end of the container. The radially inwardly curved surface of the side walls opposes forces caused by internal pressure within the cell so as to reduce and/or prevent bulging of the side walls.
