    • 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.
    • 可压缩和可变形层被致密化并层压到相对抗拉伸的材料层上。 致密化和粘合发生在一个步骤。 如用于制造电极时,例如,用于双层电容器的电极,可变形和可压缩的有源电极膜由活性炭,导电碳和聚合物制成。 电极膜可以直接结合到集电体。 或者,收集器可以涂覆有湿粘合剂层。 随后将粘合剂层干燥到箔上。 干燥的粘合剂和箔组合可以作为产品制造以供以后出售或使用,并且可以原样存储在存储卷或其他存储装置上。 将活性电极膜覆盖在金属箔上,并在诸如压延机的层压装置中加工。 层压将致密化活性电极膜并将膜粘合到金属箔上。 由于膜和箔之间的粘合,层压时活性电极膜在平行于金属箔的平面的平面上的扩展被减少或消除。
