Abstract
A sealed electrical energy storage container is provided which is cylindrical in shape and has upstanding sidewalls of generally uniform thickness. The upstanding sidewalls of the container include at least one area of reduced sidewall thickness and the reduced sidewall thickness area is designed to rupture in response to predetermined circumferential stresses occurring within the cylindrical container. The circumferential stresses occurring within the cylindrical container can be concisely calculated, allowing the thickness of the reduced thickness area to also be calculated, such that container venting will occur in response to a concise and predetermined internal pressure within the container.
