Abstract
In one embodiment, an energy storage device having a first electrode supported by a first collectors sheet; a second electrode supported by a second collector sheet; and a dielectric separator therebetween, all spirally wound together. A container houses this spiral winding, with the first collector sheet having an end in contact with the base and the second collector sheet having an end oriented towards an opening opposite to the base. A collector plate is interposed between the second collector sheet and the opening and is restrained in position by a crimp in the container. A lid is positioned in the opening and has one side in electrical contact with the collector plate and an opposite side oriented outwardly of the container. The lid is restrained in position by rolling the one or more container walls over the lid.
