NOVELTY - The method of manufacturing an electrode product useful in a manufacture of double layer capacitor e.g. supercapacitors, comprises coating (110) a first and a second surface of a current collector with a first and a second wet binder layer respectively, drying (115) the first and second wet binder layers to obtain a first and a second dry binder layer, which coats the first and second surface of the current collector, and stacking a first and a second film of active electrode material and the current collector.    USE - The method is useful for manufacturing an electrode product, which is useful in a manufacture of double layer capacitor (claimed) such as electrochemical capacitors, supercapacitors and ultracapacitors and in primary non-rechargeable battery cells, secondary battery cells and fuel cells.    ADVANTAGE - The method is capable of economically and fastly manufacturing the electrode product with a reduced number of compacting steps while densifying ductile layers.    DETAILED DESCRIPTION - The method of manufacturing an electrode product useful in a manufacture of double layer capacitor e.g. supercapacitors, comprises coating (110) a first and a second surface of a current collector with a first and a second wet binder layer respectively, drying (115) the first and second wet binder layers to obtain a first and a second dry binder layer, which coats the first and second surface of the current collector, stacking a first and a second film of active electrode material and the current collector so that the first and second dry binder layers are in contact with the first and second film respectively, laminating the current collector and the first film by pressing the collector and the film to cause the film to densify and to adhere to the first surface of the collector for obtaining a laminated electrode product, and winding the laminated current collector on a roll. The lamination consists of a single pass through a laminator, does not cause the first and second films to spread beyond the current collector, and is performed so that the first film is densified without spreading to an extent necessitating trimming. The laminating step comprises pressing the second film and the collector to cause the film to adhere to the second surface of the collector, where the second film is to be densified without spreading to an extent necessitating trimming, heating the first and second films, and processing the first and second films and current collector between rolls of the laminator. The current collector comprises a material that does not stretch significantly and causes the current collector to be capable of stretching to a lesser degree than the first film, and a metal foil. The first and second films are not separately densified. Particles of active electrode material is mixed with a polymer and a conduction promoter to form a dry powder material, which is fibrillized using a dry high-shear technique. The first and second binder layers comprise a thermoplastic. The first and second films and the collector pass between a first and a second laminator roll. The step of processing the first and second films and current collector comprises heating surfaces of the laminator rolls to a temperature of 100-300 degrees C, and setting a gap between the first and second laminator rolls so that combined thickness of the collector, the first and second films and the first and second binder layers is reduced by 30-70%. The gap setting step is performed before the film and the collector pass between the first and second laminator rolls. The rolls of the laminator apply pressure of 50-1000 pounds per linear inch to the collector and the first and second films. An INDEPENDENT CLAIM is included for an energy storage device product.
