    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： In one embodiment, a feeder for agglomerating particles comprises an enclosure that has an inlet and an outlet and that is adapted to receive a predetermined amount of the agglomerating particles. An inlet valve controls entry into the enclosure, while an outlet valve controls discharge from the enclosure. A transportation system such as an auger system carries the agglomerating particles from the outlet valve to the inner portion of a drum, and, in order to prevent a clogging of the transportation system, the speed of the transportation system is coordinated with the opening rate of the outlet valve. The drum is adapted to spread out the agglomerating particles through perforations in the drum wall, so to cause the agglomerating particles to be delivered from the inner portion of the drum to a conveyor system outside the drum at a substantially uniform rate.

    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.

    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。
