    摘要： A compressible and deformable layer is densified and laminated to a layer of a material that is relatively resistant to stretching. The densification and bonding take place in a single step. As used in fabrication of electrodes, for example, electrodes for double layer capacitors, a deformable and compressible active electrode film is manufactured from activated carbon, conductive carbon, and a polymer. The electrode film may be bonded directly to a collector. Alternatively, a collector may be coated with a wet adhesive layer. The adhesive layer is subsequently dried onto the foil. The dried adhesive and foil combination may be manufactured as a product for later sale or use, and may be stored as such on a storage roll or other storage device. The active electrode film is overlayed on the metal foil, and processed in a laminating device, such as a calender. Lamination both densifies the active electrode film and bonds the film to the metal foil. Spreading of the active electrode film in the plane parallel to the plane of the metal foil is reduced or eliminated during lamination, because of the adhesion between the film and the foil.

    摘要： Electrodes of a double-layer capacitor are designed so that sub-capacitors formed at each electrode are stressed substantially equally at the rated voltage of the double-layer capacitor. In an exemplary embodiment, each electrode includes a current collector and an active electrode layer, such as a layer of activated carbon. The electrodes are held apart by a porous separator, and the assembly is immersed in an electrolyte. The thicknesses of the active electrode layers differ, resulting in asymmetrical construction of the capacitor. Different thicknesses cause the sub-capacitors to have different capacitances. When voltage is applied to the double-layer capacitor, the voltage is divided unequally between the unequal sub-capacitors. Properly selected thicknesses allow the voltages at the sub-capacitors to stress equally each sub-capacitor. The rated voltage of the double-layer capacitor can then be increased without overstressing the sub-capacitors.

    摘要翻译： 设计双层电容器的电极，使得在每个电极处形成的子电容器在双层电容器的额定电压下基本相等地受到应力。 在示例性实施例中，每个电极包括集电器和有源电极层，例如活性炭层。 电极通过多孔分离器分开，并将组件浸入电解质中。 有源电极层的厚度不同，导致电容器的不对称结构。 不同的厚度导致副电容器具有不同的电容。 当电压施加到双层电容器时，电压在不等的子电容器之间被不均匀地分压。 正确选择的厚度可使子电容器的电压同样对每个子电容器施加压力。 然后可以增加双层电容器的额定电压，而不会对副电容器产生过应力。

    摘要： An energy storage device comprises a pair of electrodes in contact with an electrolyte and a dielectric separator therebetween. The separator comprises a chelating material capable of binding parasitic to ions with the electrolyte, so to prevent the free circulation of the parasitic ions within the electrolyte. In one embodiment, the chelating material comprises chitosan, which may be provided in fibrous form and which may be included within a non-woven fabric of cellulosic and/or olefinic, or which may be instead coated on the separator or otherwise comprised in the separator. In another embodiment, the chelating material comprises chitosan, and the ion-binding capability of the chitosan is enhanced by chemically binding a chelating agent to the chitosan so to create a multi-dentate ligand that binds with the parasitic ions, particularly multi-valent metal ions, to create coordination compounds. One such chelating agent is ethylendiamine tetraacetic acid (EDTA).
