    摘要： In one embodiment, an energy storage device comprises 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 would 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.

    摘要： Composite electrodes (300) are constructed with pressure-bonding techniques instead of an adhesive. A current collector (302) is made from aluminum foil roughed on both surfaces. The surfaces of the collector can be treated to enhance adhesion to the surfaces. Layers of film (306, 307) that includes active electrode material, such as activated carbon, are fabricated and pressure-bonded to the current collector using a calendar with heated rollers. The resulting composite sheet is then processed to shape electrodes, which can be used in electrical energy storage devices, including double layer capacitors.

    摘要： An ultracapacitor design (300) minimizes the internal pressure of the cell package (320) by using gas getters (350, 352), either alone or in combination with a resealable vent (308) in the package. Reducing pressure extends the life of the ultracapacitor (300). The primary gas types generated within a particular ultracapacitor are measured under multiple possible application conditions. Such conditions may include variables of temperature, application voltage, electrolyte type, length of use, and cycles of use. The primary gas components may be determined and suitable gas getters (350, 352) for different conditions may be formulated. The gas getters (350, 352) may be packed within the ultracapacitor packages (302), formulated as part of a negative electrode, doped into the negative current collector, or layered with the negative current collector.

    摘要： Particles of active electrode material are made by blending or mixing a mixture of activated carbon, optional conductive carbon, and binder. In selected implementations, binder content in the electrode material is relatively low, typically the binder content of the mixture being between about 3 percent and about 10 percent by weight. The electrode material may be attached to a current collector to obtain an electrode for use in various electrical devices, including a double layer capacitor. The composition of the mixture increases the energy density and the integrity of the electrode.
