Abstract
A package for an electrical component that generates a gas during operation includes a selectively permeable body that allows the gas generated within the package to escape while preventing the escape of desired fluids from the package and the entrance of undesired fluids into the package. In a double layer capacitor according to the invention, the body may be a polymeric material, such as silicone rubber or polypropylene, through which carbon dioxide permeates relatively rapidly but through which water vapor permeates relatively slowly. A package including a container and an attached cover includes a resilient member disposed adjacent the periphery of the cover for dissipating forces that might be applied to an electrically insulating seal in the cover through which an electrical terminal passes.
